Question

Percy wants to buy a guitar that costs $56. He plans to save the same amount of money each week for 7 weeks. How much money should Percy save each week so that after 7 weeks he will have exactly enough for the guitar? $5 $8 $48 $64

Answer 1

Answer:

$8

Step-by-step explanation:

Let x represent the amount of money he has to save each week.

We can use this to set up an equation:

$7x=56$

Now, we have to "isolate the variable". This means we must have a resulting equation of $x=\text{something}$.

In this case, we can use the Division Property of Equality to divide both sides by 7:

$\frac{7x}{7}=\frac{56}{7}\\x=8$

Therefore he must say $8 each week for 7 weeks so that he can buy the guitar.
