Question

Joseph, Maria and Rebecca each win a prize.

Their total prize money is $30.
Joseph wins 7/12 of the $30.
Maria wins 30% of the $30.
Rebecca wins the rest of the $30.
Calculate the amount each receives.​

Answer 1

Joseph: $ 17.5 ; Maria: $ 9 ; Rebecca: $ 3.5

Explanation:

Joseph:
`\frac7{12}\cdot30=\frac72\cdot5=\frac{35}2=\$\,17.5`

Maria:
`30\%\cdot30=0.3\cdot30=\$\,9`

Rebecca: 30 - 17.5 - 9 = $ 3.5
