You saved $20 per week to purchase one of three bikes in the store near your home. The starting price for the bikes is $130. Write and solve an equation to find the numbers of weeks you need to save money to purchase a bike.
Your parents give you $60 to help you buy the new bike. How does this change your answer to part 1? Explain.

4 weeks

Step-by-step explanation:

basic math

6.5 weeks without parental help, 3.5 weeks with help from your parents.

Step-by-step explanation:

The Equation is:

Y = 20x

Y = Starting price for bikes

X = # of weeks

Therefore:

$130 = 20x

This can be simplified by solving for x

x = 130/20

x = 6.5 weeks

If your parents gave you $60 to help buy the bike the equation would be written as:

Y = 20x + 60

$130 = 20x + 60

Subtract 60 from both sides to get:

$70 = 20x

Solve for x

x = 70/20

x = 3.5 weeks
