20 pts and a ! a store is having a sale on jelly beans and trail mix. for 6 pounds of jelly beans and 2 pounds of trail mix, the total cost is $ 12 . for 3 pounds of jelly beans and 5 pounds of trail mix, the total cost is $ 15 . find the cost for each pound of jelly beans and each pound of trail mix.

The cost of Jelly Beans =

The cost of Trail Mix      =

Step-by-step explanation:

Given the cost of 6 pounds of Jelly Beans and 2 pounds of trail mix is $12.

Also, the cost of 3 pounds of Jelly Beans and 5 pounds of Trail mix is $15.

Call the cost of one pound of Jelly beans as J

And cost of one pound of Trail Mix as T.

Now, converting the given data to mathematical form, we would have:

Dividing through out by 2 we have:

To solve (1) and (2), subtract the two equations which will give us:

⇒                                            T = 9/4

Substituting the value of T in (1), we have:

∴                                               J  = 5/4

Part A: Total cost = 10 + 4s

Part B: Solving for s = 2

10 + 4 * 2 = US$ 18

Correct statement and question:

Write an expression to represent admission to a zoo of $10.00 and the cost of special exhibits s at $4 each. Evaluate your expression when s = 2.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Admission to the zoo = US$ 10

Special exhibit cost (s) = US$ 4

2. Evaluate your expression when s = 2

Total cost = Cost of admission + (s) * Special exhibit cost

Total cost = 10 + (s) * 4

Total cost = 10 + 4s

3. Solving for s = 2

10 + 4s

10 + 4 * 2 = US$ 18
