Answer:
$2.17 per battery
Step-by-step explanation:
RATE: 6:13
A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate by dividing each term by the lower number to make it 1.
Divide 13 by 6
$2.17 a battery
UNIT RATE: $2.17:1
