Vilka [71]3 years ago
5 0

Answer:

20 questions.

Step-by-step explanation:

Let  x  be the number of questions on the quiz.

85 %  means  85  out of  100  (or  85/ 100  )

85/ 100   = 3/x

--->100-85=15

--->15/3=5

--->100/5=20  

Meaning each question was worth 5% and there were 20 questions.

Christmas candy and items are 80% off at Walgreens. Lacy got 3 rolls of wrapping paper originally priced at $4.99 each and a box
Maslowich

Answer:

A. $3.59

Step-by-step explanation:

Okay so wrapping paper 4.99 she got three. So we would take 4.99 and subtract 80%. We would get 0.998. We multiply this by three because that's how many she got. After multiplying it's 2.994, rounded just 2.99. She payed 2.99 for wrapping paper. Now with the candy canes, we take 2.99 and subtract 80%. 0.59. Added we get 3.58, and we can go ahead and round that up to $3.59. Before tax she payed $3.59.
