Which of the following options is a better purchase for a bicycle? Option 1: A cash sale for $88
stellarik [79]

<u><em>Answer:</em></u>

Option 3

<u><em>Explanation:</em></u>

<u>To get the value of the cheapest bike, best option, we will calculate the total cost of each bike:</u>

<u>i- Option 1:</u>

Total cost = $88

<u>ii- Option 2:</u>

$5 down payment and $8 per week for 10 weeks

Total cost = 5 + 8(10) = 5 + 80 = $85

<u>iii- Option 3:</u>

$12 down payment and $5 per month for 12 months

Total cost = 12 + 5(12) = 12 + 60 = $72

<u>iv- Option 4:</u>

$20 down payment and $20 per month for 12 months

Total cost = 20 + 20(12) = 20 + 240 = $260

<u>Now, from the above calculations, we can conclude that:</u>

The best price would be that of option 3 ($72). It is the lowest price compared to other option.

Hope this helps :)
