Problem Solving

7. Each pair of tennis shoes costs $25. If Andrea has
four $5-bills, does she have enough money to buy
one pair? Write a number sentence. Then solve.

Answer 1

well i will do step by step first
she has 4 5$ = 20 $
20 does not =25$
answer= andrea will not have enough money because she has 20$ which is 5 dollars less than the price

Answer 2

No she doesn´t.

Explanation:

So in order to solve this you just have to create an inequality, x is the number of bills that ANdrea has so if she has enough bills she could buy the pair of shoes:

5x-25=y

If y>0 then she could buy her shoes:

5x-25=y

5(4)-25=y

y=-5

Since -5 is not greater than 0 then she can´t afford the pair of shoes.
