Tiana buys a new cell phone with a retail price of $80.00.

frutty [35]

Answer:

$85.60

Step-by-step explanation:

We add the percentage of sales tax to the total. This means we are paying 100% + 7% tax, or 107%.

107% = 107/100 = 1.07; this gives us

80(1.07) = 85.60.

This diagram shows the dimensions of a plastic tab

Aleksandr-060686 [28]

Answer:

2340 mm

Step-by-step explanation:

We know that since the rectangular prism has a square base, the length and width are equal

So we have V = 10 * 10 * 15

For the small rectangular slab we can subtract 10 from 40 to get 30 for the length

Thus we have V = 30 * 4 * 7

Hope this helps
