$8.48

Step-by-step explanation:

Total of Items:

Add up the prices of all the items he bought

soup+oranges+newspaper

1.99+3.49+2.50=7.98

$7.98

Sales Tax:

Multiply his total by the sales tax rate

7.98*6.25%

Convert 6.25% to a decimal

6.25/100=0.0625

7.98*0.0625=0.49875

0.49875

Total With Tax

Add the tax to his total without tax

7.98+0.49875=8.47875

Round to the nearest cent, or hundreth

$8.48

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
