8 friends started a business. They will wear either a baseball cap or a shirt imprinted with their logo while working. They want to spend exactly $36 on the shirts and caps. Shirts cost $6 each and caps cost $3 each. Write a system of equations to describe the situation. Let x represent the number of shirts and y represent the number of caps.Graph the system. What is the solution and what does it represent?

Answers

For this case, the first thing we must do is define variables.

We have then:

y: number of caps

x: number of shirts

We now write the system of equations that represents the problem:

The graphical solution of the system of equations (see attached image) is:

Therefore, we have 4 shirts and 4 caps.

Answer:

See attached image for the graphic

number of caps = 4

number of shirts = 4

We can write this system of equations:

6x + 3y = 36
x + y = 8

If you graph this, it gives you a solution of (4, 4)

This tells us that the friends must buy 4 shirts and 4 caps in order to spend exactly $36 and to have 8 items total.

1. You can do 90 sit-ups in 2 minutes. Your friend can do 135 sit-ups in 3 minutes. Do these rates form a proportion? Explain2. The ratio of quarters to dimes in a coin collection is 5:3. You add the same number of new quarters as dimes to the collection.
a. Is the ratio of quarters to dimes still 5:3?
b. If so, illustrate with an example. If not, give a counter-example.
3. You are 13 years old, and your cousin is 19 years old. As you grow older, is your age proportional to your cousin's age? Explain your reasoning

Answers

Answer:

1. The relation is proportional.

2. The ratio of quarters and to dimes will not remain 5 : 3.

3. y = 6 + x, Hence, not proportional.

Step-by-step explanation:

1. I can do 90 sit-ups in 2 minutes and my friend can do 135 sit-ups in 3 minutes.

If we consider t as the time in minutes and n as the number of sit-ups, then we can write (2,90) and (3,135) as two ordered pairs.

So, the relation between t and n will be

$(n - 135)/(135 - 90) = (t - 3)/(3 - 2)$

⇒ n = 45t

Therefore, the relation is proportional.

2. The initial ratio of quarters to dimes was 5:3. If I add the same number of quarters and dimes to it then,

a) The ratio of quarters and dimes will not still be 5 : 3.

b) Let, the number of quarters was 5 then the number of dimes was 3. {As the ratio was 5 : 3}

Now, we add 3 new quarters and 3 new dimes in the collection. then, finally, the number of quarters will be (5 + 3) = 8 and the number of dimes will become (3 + 3) = 6.

Therefore, the new ratio will become 8 : 6 = 4 : 3 which is not equal to 5 : 3.

3. I am 13 years old, and my cousin is 19 years old.

So, if my age is given by x and that of my cousin is y, then

y - x = 19 - 13

⇒ y - x = 6

⇒ y = 6 + x

This relation will continue as the year passes. So, the relation is not proportional as the relation is not like y = kx. (Answer)
