Question

Kaya brought $30 to the mall. She spent $7.28 on food, and $18.94 on a necklace. How much does she have left?

Answer 1

$3.78

Explanation:

30 dollars minus 7 dollars and 28 cents is twenty-two and seventy-two cents, then minus another eighteen and ninety-four cents, would end up at three dollars and seventy-eight cents.

Answer 2

`\boxed{\$3.78}`

Explanation:

To find out how much money does Kaya have left, we need to subtract the total money spent from the total money brought to the mall.

In this problem, we can tell that Kaya brought $30 to the mall as stated in the question. Furthermore, the problem states that she spent $7.28 on food, and $18.94 on a necklace. This means that the sum of 7.28 and 18.94 is the money spent by Kaya.

`\$30 - (\$7.28 + \$18.94) = \text{Money remained}`

➡
`\$30 - (\$26.22) = \text{Money remained}`

➡
`\$30 - \$26.22 = \text{Money remained}`

➡
`\bold{\underline{\$3.78} = Money \ remained}}`
