Kelly pays $25/sweater wholesale.find the salling price if her mark-up is 65%?

gladu [14]

This is another way of saying what is 165% of 25, because 65% of the sweater is the markup, and you add the markup to the whole sale.
165% is 1.65 in decimal form, so $1.65*25=41.25$
$41.25$ is your answer

swati won a Computer game that she played with matt. The sum of the scores was 754. The difference of there scores was 176. How

klio [65]

<u>Answer:</u>

Swati - 465 , Matt - 289

<u>Explanation:</u>

Let Swati's score be x and Matt's score be y.

Since Swati won the game her score is obviously higher.

We are given the sum and difference between their scores which we can write as , x + y = 754 and x - y = 176.

Solving these two equations by adding them we get 2x = 930 so x = 465. Substituting x in x - y = 176 we get y = 289

Thus Swati scored 465 points and Matt scored 289 points.
