First, answer the problem in the parentheses. 2 + 3 is 5. 5 x 4 is 20. Now, we are going to find the question that has an answer of 20. A = 11 so it cant be that one. B is 9 so not that one, either. C is 14 so not that one, but D = 20 so we have found the answer. D is the correct answer.
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)](https://tex.z-dn.net/?f=7.50%3D2.95%2B13%28b%29)
To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as
![4.55=13 (b)](https://tex.z-dn.net/?f=4.55%3D13%20%28b%29)
Now, to get "b" by itself, you must divide
13 on both sides, resulting as
![.35=b](https://tex.z-dn.net/?f=.35%3Db)
This will answer your question as the cost of 1 bagel would be
$0.35 per bagel.
<span>1. B. a = -2, b = 9
2. D. x = 9, y = -4
im not sure about the other two its been forever since ive done that

Kevin has analyzed the situation well. However, he should also consider the fact that he saved $10 by only purchasing the shirt.Opportunity cost is the cost of the forgone alternative.out of the 3 choices, he only purchased 1 of the choices, the opportunity cost are the other two choices. However, he is still capable of buying the flip-flops costing $10 but he chose not to do so. He should consider it as a savings aside from it being a lost opportunity.
