A yogurt company advertises that the capacity of its yogurt containers increased by 20%. If the old container had a capacity of c ounces, which expression can be used to find the capacity of the container?

1.2c

Step-by-step explanation:

increasing by a percent means you find the percent of the original, then add it to the original.

so if 10 increases by 20% that means 20% of 10 is 2 so you add that to 10 so now it is 12.

you can write this out as x + x*.2 = x (1 +.2) = 1.2x.

So you just add 1 and the decimal form of the percent and multiply x by it. in your case you have c though so the result is 1.2c

1.2c

Step-by-step explanation:

Increased by 20% means 120% of the previous

(120/100) * c

1.2c
