A worker is hired for $80 a day on the condition that if business is slow, the worker will only receive half pay. At the end of 20 days, the worker receives $1,320. On how many days was business slow?

Answers

Answer 1

Answer: 7 slow days

You know the worker worked a total of 20 days, some at $80 per day, and some at $40 per day. After the 20 days, the worker was paid $1320.

x = days paid full time ($80)
y = days paid half time ($40)

you have two unknowns, so you'll need two equations to solve, from the problem statement, we can derive the following relationships:

($80)x + ($40)y = $1320
x + y = 20 days

x = 20 - y
80(20 - y) + 40y = 1320
1600 - 80y + 40y = 1320
1600 - 40y = 1320
1600 - 1320 = 40y
280 = 40y
y = 280/40 = 7

thus 7 days paid half time (i.e. slow days)

verify your solution is correct
y = 7
x = 20 - 7 = 13
80(13) + 40(7) = 1320 [OK]

Nina has 84 stickers. She wants to divide the stickers equally among 5 friends. How many stickers does each friend get? how many stickers are left over?

Answers

As per the concept of unitary method, each friend will get 16 stickers, and there will be 4 stickers left over.

The unitary method is a technique that helps to solve problems related to ratio and proportion. It is based on the concept of "per unit" or "per one". In this problem, we need to find out how many stickers each friend will get if we divide the total number of stickers equally among them. To do this, we can use the unitary method.

Find the total number of stickers divided by the number of friends

To divide the stickers equally among 5 friends, we need to find out how many stickers each friend will get. We can do this by dividing the total number of stickers (84) by the number of friends (5).

84 ÷ 5 = 16 with a remainder of 4

A bag of marbles has twice as many blue marbles as green marbles, and the bag has at least 54 marbles in it. At least how many green marbles does it have?

Answers

$b\ \ \ \rightarrow\ \ \ the\ number\ of\ blue\ marbles\ng\ \ \ \rightarrow\ \ \ the\ number\ of\ green\ marbles\n\nb+g \geq 54\ \ \ and\ \ \ b=2g\n\n2g+g \geq 54\ \ \ \Leftrightarrow\ \ \ 3g \geq 54\ \ \ \Leftrightarrow\ \ \ g \geq 18\n\nAns.\ At\ least\ 18\ green\ marbles.$

If we have twice as many blue marbles as green, we have 3 parts; 2 parts blue and 1 part greens. Therefore, 1/3 of the marbles are green

54/3=18
At least 18 of the marbles are green

When competing for admission to more selective four-year colleges, which of the following can be just important as a GPA?. A. Letters of recommendation. B. Personal statement. C. Community & Extra curricular activities. D. High school class size

Answers

When competing for admission to more selective four year colleges, community and extra curricular activities are important as GPA.

What is GPA?

"A grade point average is a number representing the average value of the accumulated final grades earned in courses over time. More commonly called a GPA, a student’s grade point average is calculated by adding up all accumulated final grades and dividing that figure by the number of grades awarded. This calculation results in a mathematical mean—or average—of all final grades. The most common form of GPA is based on a 0 to 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0), with a 4.0 representing a “perfect” GPA—or a student having earned straight As in every course."

Extra curricular activities help developing inter personality traits like working in team and having coordination.

These all help us building and finding yourselves, this is the reason colleges and university focus on more extra curricular activities.

That is why extra curricular are as important as GPA.

Hence, C is the correct option.
