Answer:
13 cups
Step-by-step explanation:
If the small box has 10 cups, then:
<u> (small) </u> <u> 10 cups </u> = <u> 100% </u>
(medium) x cups = 130%
Now, cross multiply:
10 (130) = x (100)
1300 = 100x
x = 13
Another way to solve this is by turning 30% into a decimal:
30/100 = 0.3
10 (0.3) = 3
Now you have 30% of the 10 cups, but you need <u>30% more</u><em> </em>than the small box, so:
10 + 3 = 13 cups
Volume of the tank = length x width x height
Volume = 15.4 x 10 x 3 = 450 in³
Volume of one gallon = 231 in³
Then we need 450/231 gallons to fill the tank, that is 450/231 = 1.95 gallons
