All computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that rep

prohojiy [21]

So the original price is "x".

the discounted price by 10% is P(x) = 0.9x.

the price minus a $150 coupon is C(x) = x - 150.

so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.

C( P(x) ) = P(x) - 150

C( P(x) ) = 0.9x - 150

A survey of 7th and 8th grade students asked whether they were in favor of or against school uniforms. The two-way table below s

Anna71 [15]

The percent of the 7th graders that are in favor of school uniforms is 42.857% which can be rounded as 42.9%.

The survey results show there are a total of 112 7th-grade students and from this total, the number of students that support school uniforms is 48.

Let's calculate the percentage 48 represents:

100% = 112
x = 48

x = 48 x 100 / 112
x = 4800 / 112
x = 42. 857

This means the percentage of 7th graders that support uniforms is 42.857% which can be rounded to
