Answer:
Average price = $3.185
Step-by-step explanation:
Given:
12 notepads = $4.20 each
25 folders = $0.80 each
3 calculators = $19.00 each
Find:
Average price
Computation:
Average price = Total cost / Total number of item
Average price = [(12)(4.20) + (25)(0.80) + (3)(19)] / [12 + 25 + 3]
Average price = [(50.4) + (20) + (57)] / [40]
Average price = [127.4] / [40]
Average price = $3.185
Answer:
57 children
54 adults
Step-by-step explanation:
Let's call x the number of children admitted and call z the number of adults admitted.
Then we know that:

We also know that:

We want to find the value of x and z. Then we solve the system of equations:
-Multiplay the first equation by -4 and add it to the second equation:


----------------------------------


Now we substitute the value of x in the first equation and solve for the variable z



When using distributive properties yes.
