A car rental company charges a flat fee of $20 plus $0.15 per mile driven. Write the equation in slope-intercept form that represents the total cost (y) based on the number of miles driven (x).

y = 0.15x + 15

y = 0.15x + 20

y = 0.15x - 20

y = 20x + 0.15

If a store sells notebooks for $2 each and has a fixed cost of $10 for supplies, write the equation in slope-intercept form for the total cost (y) based on the number of notebooks sold (x).

y = 2x + 10

y = 2x - 10

y = 10x + 2

y = 3x + 10

A gardener charges a base fee of $50 for landscaping plus $25 per hour of work. Write the equation in slope-intercept form for the total charge (y) based on the number of hours worked (x).

y = 25x - 50

y = 25x + 50

y = 50x + 25

y = 50 + 25x

A phone plan costs $30 per month plus $0.10 per text message sent. Write the equation in slope-intercept form for the total monthly cost (y) based on the number of text messages sent (x).

y = 0.10x - 30

y = 30x + 0.10

y = 0.10x + 30

y = 30 + 0.10x^2
