Sagot :

Step-by-step explanation:

1.Let x be months

200+30x=40x

10x=200

x=20

After 20months are the total costs of the plans the same.

2.when in the 21st month and after it, PlanA is a better deal, because only need to pay $30per month.(PlanB need to pay $40per month)

Answer:

1. 20 months

2. Plan A is better deal. After 20 month, the total monthly cost of plan A ($30/month) is less than plan B ($40/month)

Step-by-step explanation:

y = total cost per number of months

m = modem

x = cost

n = number of months

Plan A: y = m + xn = 200 + 30n

Plan B: y = m +xn = 0 + 40n

Q1. if total cost is the same : 200 + 30n = 40n >>> 10n = 200 >>> n = 20

Q2. After 20 month, the total monthly cost of plan A is less than plan B

Plan A = $30/month

Plan B = $40/month
