Nicholas wants to buy a new computer that is on sale for $899. His parents will loan him the money if he repays them. He has $225 in his savings account and plans to work as a camp counselor to earn money during the summer. If he earns $35 per day, how many days will Nicholas have to work in order to fully repay his parents?

20 days

Step-by-step explanation:

899- 225= 674

674÷ 35= 19.257

which you would round it up to 20 because he would have to work the extra day because you need more than less.

Option C

ANSWER:

The height of the prism is 4 cm, so option C is correct.

SOLUTION:

Given, the total surface area of a square based prism is 96 cm2.  

The base is 4.0 cm × 4.0 cm.

Let, the height of the prism be h.

We know that, square based prism will have two square faces and four rectangular faces.

Two square faces will have same dimensions and four rectangular faces will have same area.

Here those dimensions are 4cm and 4cm.

So, area of a square face = 4 x 4

= 16

Now, area of one rectangular face = height x width

= h x 4

= 4h

Now, we know that total surface area  = 96

2 x square area + 4 x area of rectangular face = 96

2 x 16 + 4 x 4h = 96

32 + 16h = 96

16(2 + h) = 96

2 + h = 6

h = 4.

Hence, the height of the prism is 4 cm, so third option is correct.
