11. Joe bought 3 pairs of jeans for $71.40. a. How much did he pay per pair? b. How much would be need to pay for 8 pairs of jeans? C. Solve by setting up a proportion

$23.80 per pair, $190.4 for 8 pairs

Step-by-step 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!

a. $23.80 per pair

b. $190.40

Step-by-step 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

3 x(65 – 48)

Step-by-step explanation:

n = 3(65-48)
