Question

Charles is saving $5 each week. He earns an extra $15 by mowing his neighbors lawn. How many weeks does he need to save in order to get $75

Answer 1

Hey there!!

Given amount of information:

1. Saves $5 every week
2. Get paid extra by $15 when he mows.

With this given information, we get to know that the number 15 is a constant and we don't know the number of weeks. Hence, it is a variable.

Let's take the number of weeks as 'w'

Let's now form a equation.

... 5w + 15 = ?

The total amount we want is $75. Hence,

... 5w + 15 = 75

... 5w + 15 - 15 = 75 - 15

... 5w = 60

... 5w/5 = 60/5

... w = 12

Hence, the number of weeks is 12.

Answer 2

He needs 12 weeks to save in order to get $75.

Given that

Charles is saving $5 each week.

He earns an extra $15 by mowing his neighbor's lawn.

We have to determine

How many weeks does he need to save in order to get $75?

According to the question

Let the number of weeks he needs to save in order to get $75 be x,

Charles is saving $5 each week.

He earns an extra $15 by mowing his neighbor's lawn.

Then

$\rm 5x + 15 = 75$

Solve for the value of x,

$\rm 5x+15 = 75\\\\5x = 75-15\\\\5x = 60\\\\x = \dfrac{60}{5}\\\\x =1 2 \ weeks$

Hence, He needs 12 weeks to save in order to get $75.
