Because there is no whole number that you can divide into both the numerator and the denominator to get a proper fraction.
The value of y is -7 because you will add 4 on both sides and adding to negatives is adding and keeping the sign of the larger number.
Step-by-step explanation:
Cost = $112
30% discount coupon on the item he's going to buy
=$112 × 30/100 (or you can write 30%)
=$168/5 ($33.6)
7% tax on the item=$112 × 7/100(or you can write 7%)
= $196/25 ($7.84)
Total amount altogether=$112 - $33.6 - $7.84
=$70.56
not sure for the answer^^
The way calculate the volume is l*w*h, 3 times 5 times 7 is 105
