2(5c+ 2) - 2c = 3(2c + 3) + 7

Mademuasel [1]

Answer:

c = 6

Step-by-step explanation:

Step 1: Write equation

2(5c + 2) - 2c = 3(2c + 3) + 7

Step 2: Solve for c

Distribute: 10c + 4 - 2c = 6c + 9 + 7
Combine like terms: 8c + 4 = 6c + 16
Subtract 6c on both sides: 2c + 4 = 16
Subtract 4 on both sides: 2c = 12
Divide both sides by 2: c = 6

A dealer sold 200 tennis racquets. Some were sold for $33 each, and the rest were sold on sale for $18. The total receipts form

Mumz [18]

120 tennis racquets were sold for $ 18 each

Solution:

Let x = number that sell for $18 each

Then, 200 - x = number that sell for $33 each

The total receipts form these sales were 4800 dollars

Thus we frame a equation as:

number that sell for $18 each x 18 + number that sell for $33 each x 33 = 4800

$x \times 18 + (200-x) \times 33 = 4800\\\\Solve\ the\ above\ equation\ for\ x\\\\18x + 6600 - 33x = 4800\\\\Move\ the\ variables\ to\ one\ side\\\\18x-33x = 4800-6600\\\\-15x = -1800\\\\Divide\ both\ sides\ of\ equation\ by\ -15\\\\x = 120$

Thus 120 tennis racquets were sold for $ 18 each
