This year, 1,272 students enrolled in night courses a a local college. last year only 1,200 students enrolled. what was the percent increase in the enrollment? which operation will you use in your first step?

The percent increase in enrollment is 6 %

The operation used in first step is finding the difference between final value and initial value

Given that This year, 1,272 students enrolled in night courses a a local college

Last year only 1,200 students enrolled.

To find: percent increase in the enrollment

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

Here initial value (last year) = 1200 and final value(this year) = 1272

Substituting the values in above formula,

Thus percent increase is 6 %

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
