Jake bought a shirt on sale for $80. the sale price of the shirt had been reduced by $40. what was the percent markdown on the shirt

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
