Option C) Smith have to pay $180 at the time of purchase.
<u>Step-by-step explanation:</u>
Mrs. Smith wants to use an installment plan to buy a washing machine and dryer set priced at $1,500.
- Therefore, the total cost = $1500
- The down payment for the installment plan is 12%.
We need to find the payment amount at the time of purchase.
This can be calculated by finding the 12% of the total price $1500.
Smith have to pay at the time of purchase = 12% of 1500
⇒ (12/100) × 1500
⇒ 12 × 15
⇒ 180
Hence, option C) $180 is the amount need to be paid by the Smith at the time of purchase.
Ana, Betty and Carol in the ratio of 2:3:5 respectively
mom cut the $600 in (2+3+5) 10 parts
and gave 3 parts to betty
so B got 600 : 10 x 3 = $180
