Evaluate the expression when y=4.

y2−8=

y=4

4*2-8=

8-8=0

Step-by-step explanation:hope it is correct

If it’s a square root than it’s
4x4=16
16-8=6

If it’s a 2
4x2=8
8-8=0

So it’s 6 if it’s y to the square root or it’s 0 if it’s y times 2

Her refund would be $5,681.20.

The problem says that Laura paid the estimate above, which is 28%.
0.28 x 134350 = 37618

However, she had some deductions.
134350 - 4000 - 12200 - 4090 = 114060

So, to find the tax on this amount, we multiply it again by 0.28.
0.28 x 114060 = 31936.8

The amount of the refund will be the difference.
37618 - 31936.8 = 5681.2
