Answer:
Step-by-step explanation:
total price was reduced by $ 7
let x = the total price........ x - 7
he bought 10.....and it cost him $ 130
10(x - 7) = 130
10x - 70 = 130
10x = 130 + 70
10x = 200
x = 200/10
x = 20 <====== original price
X-1 + x + x+1 = 42
3x = 42
x = 14
the numbers are 13 14 and 15
11/12 divided by 5/7 should be 0.02619047619 you can double check it though
