A phone company offers a plan that costs $50 per month plus $0.10 per text message sent. Write the equation in slope-intercept form for the total cost (C) based on the number of text messages (t). Identify the slope and intercept.
C = 0.10t + 50; Slope: 0.10, Intercept: 50
C = 50t + 0.10; Slope: 50, Intercept: 0.10
C = 0.05t + 50; Slope: 0.05, Intercept: 50
C = 0.10t + 100; Slope: 0.10, Intercept: 100

A gym charges a monthly membership fee of $40 and an additional $5 for each class attended. Write the equation in slope-intercept form for the total cost (C) based on the number of classes (c). What do the slope and intercept represent?
C = 5c + 30; Slope = 5, Intercept = 30
C = 4c + 40; Slope = 4, Intercept = 40
C = 5c + 40; Slope = 5 (cost per class), Intercept = 40 (monthly fee)
C = 10c + 20; Slope = 10, Intercept = 20

Two friends are saving money for a concert. Friend A saves $15 a week, while Friend B saves $10 a week. Write the equations in slope-intercept form for each friend's savings (S) based on the number of weeks (w). What is the slope for each friend?
Friend B: S = 15w (slope = 15)
Friend A: S = 15w (slope = 15), Friend B: S = 10w (slope = 10)
Friend A: S = 10w (slope = 10)
Friend A: S = 20w (slope = 20)

A bakery sells cupcakes for $3 each and cookies for $2 each. If a customer buys a total of 10 items for $24, write a system of equations in slope-intercept form to represent the situation. Identify the slope and intercept of each equation.
y = -0.5x + 5 (slope -0.5, intercept 5)
y = -3x + 15 (slope -3, intercept 15)
y = -2x + 8 (slope -2, intercept 8)
1) y = -1x + 10 (slope -1, intercept 10), 2) y = -1.5x + 12 (slope -1.5, intercept 12)

A school is selling tickets for a play. The tickets cost $8 each, and they also have a special deal where you can buy 3 tickets for $20. Write the equations in slope-intercept form for both pricing options. What do the slopes represent?
y = 8x for regular tickets; y = (20/3)x for special deal tickets.
y = 10x for regular tickets; y = (25/3)x for special deal tickets.
y = 12x for regular tickets; y = (30/3)x for special deal tickets.
y = 5x for regular tickets; y = (15/3)x for special deal tickets.

A delivery service charges a base fee of $5 plus $1.50 per mile. Write the equation in slope-intercept form for the total cost (C) based on the distance (d) in miles. Identify the slope and intercept.
C = 3d + 2; Slope: 3, Intercept: 2
C = 1.50d + 5; Slope: 1.50, Intercept: 5
C = 1.50d + 10; Slope: 1.50, Intercept: 10
C = 2d + 5; Slope: 2, Intercept: 5
