grandymaker [24]

Answer:

Shop 1 = $260 + $20m

Shop 2 = $140 + $30m

Step-by-step explanation:

m = number of months payments are made

Total payment made = down payment + monthly payment

Shop 1 requires $260 down and a monthly payment of $20.

Shop 1 = $260 + $20m

= 260 + 20m

Shop 2 requires $140 down and a monthly payment of $30.

Shop 2 = $140 + $30m

= 140 + 30m

The equations that represent the payments plans are:

Shop 1 = $260 + $20m

Shop 2 = $140 + $30m
