What is a 30 percent increase followed by a 15 percent decrease?

10.5 increase.

Step-by-step explanation:

Suppose we have  100 .

30 percent increase = 100 + 0.3 * 100 = 130.

Followed by a 15% decrease = 130 - 130*0.15

= 110.5

which is a 10.5% increase on the original amount.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
