(A) Option 1
(B) Option 2
(C) Option 3
(D) Option 4

Answer 1

Option 3: $12 down with equal payments of $5 for 12 months

Step-by-step explanation:

In option 1 :

The cost is $ 88,

In option 2 :

Down payment = $ 5,

Weekly payment = $ 8,

Number of weeks = 10,

So, the total cost = 5 + 8 × 10 = 5 + 80 = $ 85,

In option 3 :

Down payment = $ 12,

Monthly payment = $ 5,

Number of months = 12,

So, the total cost = 12 + 5 × 12 = 12 + 60 = $ 72,

In option 4 :

Down payment = $ 20,

Monthly payment = $ 20,

Number of months = 12,

So, the total cost = 12 + 20 × 12 = 12 + 240= $ 252

∵ 72 < 85 < 88 < 252

Hence, option 3 is better.
