Integer 1 = n
integer 2 = n + 1
integer 3 = n + 2
n + (n + 1) + (n + 2) = 141
3n + 3 = 141
3n = 141 - 3
3n = 138
n = 138/3
n = 46 --(1st integer)
n + 1 = 46 + 1 = 47 --(2nd integer)
n + 2 = 46 + 2 = 48 --(3rd integer)
so the smallest integer is 46

Answer:
Basic fee = $14.95
1.5 dollars per quart of oil
Step-by-step explanation:
Each customer is charged a fee x (in dollars) for the oil change, plus y dollars per quart of oil used.
The oil change for the car that requires 5 quart of oil costs $22.45.
The oil change for the car that requires 7 quarts of oil costs $25.45.
Both equation having x
so make it equal and solve for y
Add 7y on both sides
subtract 22.45 from both sides
now plug in 1.5 for y and solve for x
