Answer:

$23.80 per pair, $190.4 for 8 pairs

Explanation:

a. assuming each pair of jeans is the same price, just divide the total by 3. the price per pair is 71.40/3, which is $23.80 per pair

b. simply multiply the price of one pair of jeans, as found above, by 8. 23.80*8 is $190.4 for 8 jeans

hope this helped!

Answer:

a. $23.80 per pair

b. $190.40

Explanation:

3 pairs of jeans for $71.40

so the proportion is 71.40:3 = 23.8:1

23.8:1 = 8(23.8):8(1) = 190.4:8
