Question

Decide whether the rates are equivalent. Maria saves $50 in 4 months.

Ralph saves $60 in 5 months ​

Answer 1

The rates are not equivalent since Maria saves $0.50 more per month than Ralph.

Explanation:

We can determine if two rates are equivalent by comparing the rates at which they save per month.

Maria's savings per month:

Both 50 and 4 can be divided by 2, which gives us 25/2. As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.

Ralph's savings per month:

Both 60 and 5 can be divided by 5, which gives us 12. Thus, Ralph saves $12 per month.

Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.
