Answer:

D.) eCafé, the equation is C = $0.20M + $7.00, and I'll save $2.00

Step-by-step explanation:

Log-On Café: $6.25 plus $0.25 for every minute online

c = 6.25 + .25m

cost for 55 minutes

c = 6.25 + .25 (55)

c = 6.25 + 13.75

c = 20.00

eCafé: $7.00 plus $0.20 for every minute online

c = 7 + .2m

cost for 55 minutes

c = 7 + .2 (55)

c =7+11

c = 18

The e cafe is less expensive (20-18) by 2 dollars
