Answer:

if a is 1 more than b it can be expressed as so:

a=b+1

b+1=a

b^2+1=a^2

b^2=a^2-1

b=a-1

if b if 1 then a is 2

b+1=a

-a+b=-1

a-b=1

a=2, b=1

a=b+1

a+b=3

1+2=3

Ivy’s father wanted to keep track of the gas he purchased for 3 weeks. He purchased 22.5 gallons during the first week and 19.71

wlad13 [49]

Total amount of gas purchased by Ivy's father in the first week = 22.5 gallons
total amount of gas purchased by Ivy's father in the second week = 19.71 gallons
Let us assume the amount of gas purchased by Ivy's father in the third week = x
The total quantity of gas purchased in 3 weeks by Ivy's father = 61.75 gallons
Then
22.5 + 19.71 + x = 61.75
42.21 + x = 61.75
x = 61.75 - 42.21
= 19.54 gallons
So 19.54 gallons of gas was bought by Ivy's father in the third week
