Summary of reflecting, stretching and compressing the graph of a parabola:

y = a(x-h)2+k

If a <0, then the graph will

If 0
If a>1, then the graph will?

Part 1) Each sandwich costs $.02 per cubic inch to make. What is the cost of each sandwich?

volume for cube sandwich is 125 in³
volume for pyramid sandwich is 41.67 in³

cost of each cube sandwich=0.02*125> $2.5

cost of each  pyramid sandwich=0.02*41.67> $0.83

the answers Part 1) are
a) cost of each cube sandwich is $2.5
b) cost of each pyramid sandwich is $0.83

Part 2) If each sandwich sells for $4.00 and Mr. Sammie sells 100 Cube sandwiches and 100 Pyramid Sandwiches, how much profit would Mr. Sammie make?

we know that
Profit=Sells-Costs

step 1
 find the sells
Sells=200*$4> $800

step 2
find the costs
Costs=100*$2.5+100*$0.83> $333

step 3
find the profit
Profit=Sells-Costs
Profit=$800-$333> $467

the answer Part 2) is
the profit is $467
