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?

$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

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
