Answer:
Commision rate 13%
Explanation:
The commission rate is equal to the commission as a percent of sells.
Now in our case,
sells = $2700
commission = $351
Therefore, the commission rate is equal to
12 blue marbles.
white marbles is 5X3=15
so blue is
4X3=12.
X - the percent of increase
The percent of increase is approximately 23.8%.
You know you have to divide, but you can't decide which way.
Use your units. The answer will be (money) per (can of soup), so
you know you have to divide the money by the number of cans.
(If you divided (cans of soup) by (money) then the answer you get
would be (cans) per (dollar). That's not what you need.)
(2.50) / (4 cans)
= (2.50/4) per can
= 0.625 per can .
