Answer:
Choice D
Step-by-step explanation:
Log-On-0.25x55+6.25=$20
ECafe-0.20x55+7.00=$18
ECafe saves $2
D.) eCafé, the equation is C = $0.20M + $7.00, and I'll save $2.00
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
c = 7 + .2 (55)
c =7+11
c = 18
The e cafe is less expensive (20-18) by 2 dollars
equalize the both sides of the functions
4x-5 = 2x-5
4x = 2x
2x = x
2 = 1 meaning phi
