0.8X = Final cost
Step-by-step explanation:
Given that jeans are on sale for 20% off the regular price, to determine which function would give you the total cost for purchasing a pair of jeans that costs X dollars, the following calculation must be performed:

Answer:
L = 2 4/5 feet
Step-by-step explanation:
A = L x W
6 = L x 2 1/7
divide both sides by 2 1/7
6 divided by 2 1/7 = L (is the same as multiplying by the reciprocal)
6 x 7/15 = L
L = 14/5 or 2 4/5
