Question

Ariana and her father share her college costs in a ratio of 1:4. What part did she pay of her $12,000 college costs this year?

The alternatives are as follows: a. $3,000 b. $ 2,400 c. 9,000 and d. 9,600

Answer 1

Ariana and her father share her college costs in a ratio of 1:4.
taking `x` to be the common multiple,

so, `x + 4x` = `"total cost. "`

`5x=12000`

`x=12000/5`

`x=$2400`

therefore, alternative b. $2,400 is the correct one.
