Given

--- <em>not 296</em>

Required
Simplify the expression for total earning
The total amount is derived from:


Express percentage as decimal

Now, we can solve further:


<em>Hence, the simplified expression is 1.02n</em>
You would multiply 18 machines x 16" for a total of 288 inches. You would then divide by 36 because there are 36" (or 3 feet) in a yard. The answer is 8 yards of tubing.
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.
the first answer is -7/15
the second answer is 1/2
