Question

5.) Jade's mom allows her to spend 2/5 of her $10 allowance each week. Jade is saving up for a Barbie car which cost $20 (including tax). How many weeks will she need to save to purchase the car?

Answer 1

If Jade is allowed to spend 2/5 of her $10 weekly allowance, then her weekly saving would be;

`\begin{gathered} \text{Savings}=10-((2)/(5)*10) \\ \text{Saving}=10-(4) \\ \text{Saving}=6 \\ \text{If her savings per week is \$6, then;} \\ \text{Total weeks=}(20)/(6) \\ \text{Total weeks=}3(1)/(3) \\ \text{This means she would need 4 weeks to save up} \\ \text{Because weeks cannot be fractions} \end{gathered}`

The results shows that she would need 4 weeks to save up for a Barbie car
