Answer:
$110
Step-by-step explanation:
First we would need to find out how many cans of dog food are required.
To find that you would divide 60 by 3.
60/3 = 20
You would then have to multiply that number by how much it costs for each pair of 3 cans, that being $5.50.
20 * 5.50 = $110
I think that is 90000 because you said 9 to the power of 4 and there are 4 zeroes
Step-by-step explanation:
after 60% reduction he paid 40% of its price=224

224×100=40×?
?=560
Find 100%
first pool
320=0.84 times whole
divide both sides by 0.84
380.95=whole
second is
400=0.825 times whole
divide both sides by 0.825
484.848484=whole
how much more
484.848484-380.95=103.89
2nd pool holds 103.89 ft³ more water
