Which linear equation represents the total cost in dollars, y for x tickets?

• y = 35x + 25

• y = 30x + 50

• y = 40x + 20

• y = 25x + 75

• y = 35x + 15

Printer ink costs $18.99 per cartridge. The company that sells the ink cartridges charges a flat rate shipping fee of $7.95, no matter the number of cartridges purchased in a single order.

Which linear function modes the total cost, t, for a singer order of c cartridges?

• c = 18.99t - 7.95

• c = 26.94t

• t = 18.99c + 7.95
• t = 18.99 + 7.95c

Calculators costs $49.99 per item. The company that sells the calculators charges a flat rate shipping fee of $10.95, no matter the number of calculators purchased in a single order.

Which linear function modes the total cost, t, for a singer order of c, calculators?

• c = 49.99t - 10.95

• c = 68.95t

• t = 49.99c + 10.95
• t = 10.95c + 49.99

Bananas costs $8.65 per bunch. The grocery store that sells the bunches charges a flat rate shipping fee of $12.95, no matter the number of bunches purchased in a single order.

Which linear function modes the total cost, t, for a singer order of b, banana bunches?

• b = 8.65t - 12.95

• b = 12.95t

• t = 8.65b + 10.00
• t = 8.65b + 12.95
