A store marks its merchandise up 225% from the price it pays (Hint: whoa that is MORE than DOUBLED/twice).

The store buys a bag of chips for $1.20. How much will the store charge for the bag of chips?

Answers

Answer 1
The store will charge $3.90 for the bag of chips.
Reason for this is do 1.2*225%(or 2.25) in your calculator to get 2.7.
Then take the 2.7 then add it to the original purchase cost of 1.2 to give you a total of $3.90.

A triangle is formed by intersecting lines.

What is the measure of angle x?

Answers

The sum of all angles of a triangle = 180.
So 180-90 (right angle) - 51 (other known angle) = 39
the measure of angle x would be 39°
triangles only go up to 180° and that triangle already has a 90° right angle and a 51° acute angle. so the answer is 39°
