Question

The municipal swimming pool in Nicetown has three different ways of paying for individual open swimming. Todd is trying to decide which way to pay. • Early Pay: Pay $70 before Memorial Day; swim any number of days • Deposit Plus: $15 deposit plus $4.00 per day • Daily Pay: $6.00 per day Answer the following questions: 1. Write an equation for each method of payment. Write your equations in slope-intercept form so that x is the number of days and y is the cost. a. Early Pay: b. Deposit Plus: c. Daily Pay:

Answer 1

sllope intercept form is y=mx+b
m is the slope , b is the y itnercept

so early pay
cost=70 flat rate
x=infinity
the equation would be y=70

deposit pluss
you have to pay an initial one time payment of 15 so
y=mx+15
then 4 dollars per day
4 times number of days
y=4x+15

daily pay is 6 dollars per day so 6 times number of days
y=6x



1.
a. y=70
b. y=4x+15
c. y=4x
