Question

Hashim had some money. His sister had $75.10. After Hashim gave his mother $28, he had $15.20 less than his sister. How much did he have at first?

Answer 1

Hashim originally had $87.90.

Step-by-step explanation:

To solve this problem, we can set up an equation. Let's say Hashim had x dollars initially. After giving his mother $28, he had $15.20 less than his sister who had $75.10. This can be represented as: x - 28 = 75.10 - 15.20. Solving this equation, we can find the value of x, which is the initial amount of money Hashim had.

x - 28 = 75.10 - 15.20

x - 28 = 59.90

x = 59.90 + 28

x = 87.90

Therefore, Hashim originally had $87.90.

Answer 2

$87.90

Step-by-step explanation:

Let the amount of money Hashim had be $Y. As such, if he gives his mother $28, he would have $Y - $28 left.

If he had $15.20 less than his sister and his sister had $75.10, then we can say that what he had left $Y - $28 is equivalent to the difference between $75.10 and $15.20.

This is

$Y - $28 = $75.10 - $15.20

Y = $28 + $75.10 - $15.20

= $87.90
