3 1/2 gallons of white paint is 61.25
1 3/4 gallons of blue paint is 33.25
so the total is 94.50 dollars
Let's name Janet's age x
julie is then x-3 years old
and the brother is x-3-8=x-11
and all three of them: x+x-3+x-11 are 55
so we count:
2x-3+x-11=55
3x-3-11=55
3x-14=55
add 14 5o both sides:
3x=69
divide by 3:
x=23
so Janet is 23, Julie is 23-3=20 and the brother is 20-8=12 years old!
