Answer:
The cost per square inch of the pie is $0.111 or 11 cents
Step-by-step explanation:
The shape of a pie is circular.
The area of a circle (pie) = πr²
From the question ,
Diameter = 12 inches
Radius = Diameter/2
Radius = 12 inches/2
Radius = 6 inches.
Hence, the area of the pie = π × 6²
= 113.09733553 square inches
A pie costs $12.55
The cost per square inches of the pie is calculated as:
113.09733553 square inches = $12.55
1 square inch = $x
Cross Multiply
113.09733553x = $12.55
x = $12.55/113.09733553
x = $0.1109663631
Approximately
x = $0.111
Therefore, the cost per square inch of the pie is $0.111 or 11 cents
Answer:
The total cost = $1,099
It would take 100 days
Step-by-step explanation:
Let
x = number of days
Cost of BT&T Cellular = 899 + 2x
Cost of Revizon Electronics = 799 + 3x
Equate the cost of both cell phone services.
899 + 2x = 799 + 3x
899 - 799 = 3x - 2x
100 = x
x = number of days = 100 days
Cost of BT&T Cellular = 899 + 2x
= 899 + 2(100)
= 899 + 200
= $1,099
Cost of Revizon Electronics = 799 + 3x
= 799 + 3(100)
= 799 + 300
= $1,099
