First translate the question into an equation.
"What percent" means x/100, "of 40" means times 40, "is 14" equals 14.
So we have (x)(40) = 14 or 40x = 14.
Dividing both sides by 40, we find that x = 0.35.
Now, we want to write our answer as a percent.
So we move the decimal 2 places to the right and we have 35%.
This is an expression if she only gets pedicure
y = 35
If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5
So the expression would be
y = 35 + 2.5x
y = 2.5x + 35
You divide 12 by 1.56 because a dozen is 12 of something. This gives you about 8 cents per
183/3: 61mph
The answer would be 61mph.

There are 27 total.
Since there are 27 in all, it's best if each small rectangle value is 3.
