Question

During a cat food sale, a pet store sells 220 cans of cat food. At the end of the

sale, the store has 80% of the original number of cans of cat food. How many
cans of cat food are left?

Answer 1

To determine the number of cans left, we solve for the original amount of cans where selling 220 cans leaves 80% of the stock. Then, we calculate 80% of the original total to get the number of cans remaining.

Step-by-step explanation:

The question is asking how many cans of cat food are left if a pet store sells 220 cans and has 80% of the original number of cans left. To find the answer, we need to determine what 100% would represent if 80% equals the remaining cans after 220 were sold.

We can set up the equation where the original amount of cans is X, and after selling 220 cans, 80% of X is left:

80% of X = X - 220

To find X, we rearrange the equation:

X = (X - 220) / 0.8

By solving this equation, we find the original number of cans (X) and then calculate 80% of it to obtain the number of cans left after the sale.

Answer 2

44 cans

Step-by-step explanation:

To find 80%, just multiply 220 by 0.8

220 x 0.8 = 176.

Now, take 220 and subtract 176.

220-176 = 44

44 cans are left over. Hope this helps.
