120 tennis racquets were sold for $ 18 each
<em><u>Solution:</u></em>
Let x = number that sell for $18 each
Then, 200 - x = number that sell for $33 each
<em><u>The total receipts form these sales were 4800 dollars</u></em>
Thus we frame a equation as:
number that sell for $18 each x 18 + number that sell for $33 each x 33 = 4800
Thus 120 tennis racquets were sold for $ 18 each

b)
2(9) * 3 - 12
18 * 3 = 54 - 12 = 42

4(9) - 18 + 12
36 - 18 = 18 + 12 = 30
