Question

&X=2*Example 4*: Jillian saved x dollars so that she could buy her mom a birthday present. Unfortunately, she had to spend a third of it on lunch, but then she lent $5 to her brother. If she now has $16, how much money did she begin with?115fYS -16

Answer 1

$ 31.5

Explanation:

Let x be the saving value of Jillian, we can establish the following equation according to the statement:

`16=x-(x)/(3)-5`

We solve for x

`\begin{gathered} 16=(2)/(3)x-5 \\ (2)/(3)x=16+5 \\ x=(3)/(2)\cdot21 \\ x=31.5 \end{gathered}`

Originally Jillian had saved $ 31.5
