Question

17. A company charges $3 for each balloon in an arrangement and a $10 delivery fee. You have $40 to spend. How

many balloons can you afford? Write an equation and solve
steps ?

Answer 1

y=3x+10, x=10 balloons

Explanation:

The slope is 3 because for every balloon you buy, you get charged $3. The y-intercept is 10 because of the delivery fee. Substitute 40 for y and solve.

y=3x+10

40=3x+10

30=3x

x=10
