Answer:
$36
Step-by-step explanation:
1. Determine the surface area of the largest jaw breaker
Surface area of a sphere = 4πr²
4 x 3.14 x 2² = 50.24in²
2. Determine the surface area of the new jaw breaker
4 x 3.14 x 6² = 452.16 in²
3. Determine the cost per area
4/ 50.24
4. Determine the price for the new jaw breaker
4/ 50.24 x 452.16 = $36
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.
Answer:
Banners: 4
Paper lanters: 3
Bags of Balloons: 6
Garlands: 11
Step-by-step explanation:
Banner: 4*5.25= $21
Paper lantern: 6.50*x=?
Balloons: 5*x=?
Garland: 3.50*x=?
Paper lantern: 145.50/6.50= $22.3
22.3/6.50= 3.4 round to 3
3 paper lanterns
Balloons: 145.50/5= $29.1
29.1/5= 5.8 round to 6
6 packs of balloons
Garland: 145.50/3.50= $41.5
41.5/10= 4.15
4.15+7=11.15 round to 11
11 garlands
