Question

Find the unit rate for the situation: Corrin has twin boys. She buys a box ot

Answer 1

(1) Given:

Given that Corrin has twin boys. She buys a box of 10 toy cars to share evenly between them.

We need to determine the unit rate of toy cars for one boy.

Unit rate:

The unit rate for toy cars for one boy can be determined by dividing the total number of cars by the total number of boys.

Thus, we have;

$Unit \ rate=\frac{10}{2}$

$Unit \ rate=5$

Thus, the unit rate is 5 cars per boy.

Hence, Option b is the correct answer.

(2) Given:

Given that the Belle works at a donut shop. They sell a box of donut holes for $1.80. There are 20 donut holes in the box.

We need to determine the unit rate.

Unit rate:

We need to determine the cost of one donut hole in the box.

The cost of one donut hole can be determined by dividing the cost of box of donut holes by the total number of donut holes in the box.

Thus, we have;

$Unit \ rate=\frac{1.80}{20}$

$Unit \ rate=0.09$

Thus, the unit rate is $0.09 per donut hole.

Hence, Option a is the correct answer.
