Question

Kevin earned $80. Out of his earnings, he spent $685 on shopping, $512 on food, and $225 for taxi. Find the remaining amount.

Answer 1

SOLUTION

To get the remaining amount, we subtract all the other cost from the amount he earned.

This means, the remaining amount becomes

$80-\frac{68}{5}-\frac{51}{2}-\frac{22}{5}$

This becomes

$\begin{gathered} \frac{80}{1}-\frac{68}{5}-\frac{51}{2}-\frac{22}{5} \\ \\ \text{LCM of the denominators = 10 } \\ \\ \frac{800-136-255-44}{10} \\ \\ \frac{365}{10} \\ \\ =\frac{73}{2}\text{ dollars} \end{gathered}$
