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!
Answer:
Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).
Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).
