Answer:

1008

Step-by-step explanation:

If 4/5 of eighth graders, or 80%, are enrolled with class, there are still 20% of students that didn't study. That means you add 168, the 20%,  and you'll get 1008.

Sylvie bought 13 bagels and a container of cream cheese.Each bagel cost the same price.The cream cheese cost $2.95.Sylvie spent
Taya2010 [7]
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50 <u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

7.50=2.95+13(b)

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as 

4.55=13 (b)

Now, to get "b" by itself, you must divide 13 on both sides, resulting as

.35=b

This will answer your question as the cost of 1 bagel would be $0.35 per bagel.
