Answer:
Unit rate defined as the rates are expressed as a quantity 1 such that 4 miles per hour or 3 meter per second.
As per the statement:
if you paid $64.70 per month.
⇒Unit rate per month = $64.70
We have to find how much would you pay for an item for 48 months.
[tex]\text{Pay for an item} = \text{Unit rate per month} \times 48[/tex]
Substitute the given values we have;
[tex]\text{Pay for an item} = 64.70 \times 48 = \$3,105.60[/tex]
Therefore,, $3,105.60 would you pay for an item for 48 months.
