Question

Tammy has $20 to spend at the movie theater. She spends $9.50 on a movie ticket. If the snack counter sells bags of candy for $3.50 each, how many bags of candy can Tammy buy with the money she has left?

Answer 1

Answer:3

Explanation:

20-9.50=11-3.50

Answer 2

Answer is 3
she can buy exactly 3 bags of candy


Step by step

We know she has up to $20 to spend (y)
We know her one time ticket cost is $9.50 (b)
We know candy is $3.50 per bag (m)
We are looking for “x” the variable

We can use y intercept formula to find your rate of bags of candy she can buy

y = mx + b

20 = 3.50x + 9.50

Subtract 9.50 from both sides to isolate x

20 - 9.50 = 3.50x + 9.50 - 9.50
Combine

10.50 = 3.50x

Divide both sides by 3.50 to solve for x

10.50 / 3.50 = 3.50/3.50 x

3 = x
so she can buy exactly 3 bags of candy
