Answer:
$220
Step-by-step explanation:
Make a proportion
We know that 99 over some number (x) must equal 45%
99/x=45/100
Cross multiply
45x=9,900
Divide by 45 on both sides
x=220
So, the tablet costs $220

Step-by-step explanation:

We need to find the surface area of the box. For this, we will do 2(L×W) + 2(L×H) + 2(H×W); Since each has a corresponding side, we multiply it by 2.
Let's find it with plugging it in.
2(2×1) + 2(2×1) + 2(1×1)
4+4+2=10
Now the surface area is 10 ft², let's just multiply .8 by that to find the price.
.8×10= 8
It'll cost $8 for Joseph to cover the box with wrapping paper.
