Answer:
The total number of hours = 35 hours.
Step-by-step explanation:
The annual fee of Calm Spa = $125
Per hour charge of Calm Spa = $10
Annual fee of Relax Spa = $230
Per hour charge of Relax Spa = $7
Now we have to find the number of hours for which both have same cost.
Let the number of hours = x
Thus, 125 + 10x = 230 + 7x
10x-7x = 230 – 125
3x = 105
x = 35
The total number of hours = 35 hours.
Part 1) <span>Each sandwich costs $.02 per cubic inch to make. What is the cost of each sandwich?
</span>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) <span>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?
</span>
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
