Option B: Increase savings each month by $100 from their original plan
Answers
Answer:
Neither option A nor option B will allow them to meet their goal.
Step-by-step explanation:
Consider the provided information.
The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal.
They set aside the same amount each month and after 7 months discovered they have saved $3,100. Now he left with 5 months (∴7+5=12 months)
Let x is the amount he was saving each month. He saved x amount for 7 months and after 7 months he has $3100.
He saved approximately $442.86 each month.
Option A Save the original amount each month but put the pool in one month later than originally planned.
That means the number of month he has now 5+1=6.
Now find how much he can save in 6 months if he save $442.86 per month.
6×442.86=2657.16
Now add his all savings as:
$3100+$2657.16=$5757.16
Thus, the option A will not allow him to meet his goal.
Now consider the option B) Increase savings each month by $100 from their original plan.
Previously he was saving $442.86 each month now increase this number by $100.
$442.86+$100=$542.86
In 5 months he can save:
5×542.86=$2714.3
Now add his all savings as:
$3100+$2714.3= 5814.3
Thus, the option B will not allow him to meet his goal.

What is the product of two algebraic expressions?
When two algebraic expressions are multiplied, the result is called the product, and the two expressions making up the product are called factors and multiplicands.
The multiplication of two algebraic equations can be expressed as a × b.
The product of 3a + 5 and 2a2 + 4a – 2 is determined in the following steps given below.
Hence, the product of 3a + 5 and 2a2 + 4a – 2 is .

Answer:
6a3 + 22a2 + 14a - 10
Step-by-step explanation:
(3a + 5) x (2a^2 + 4a - 2)
= 3a(2a^2 + 4a - 2) + 5(2a^2 + 4a - 2)
= 6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10
= 6a^3 + 22a^2 + 14a - 10

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have an equation in one variable:
(6.4)x = 32
Divide by 6.4 on both sides in order to find the value of x:
[(6.4)x]/6.4 = 32/6.4
x = 5
Thus, in order to solve the equation (6.4)x = 32 divided by 6.4 on both sides option (B) is correct.
