Chicago Pizza charges $10.49 for a medium 14" pepperoni pizza and NY Pizza charges $20.99 for an x-large 18" pepperoni pizza.

Question #1. Find the cost per square inch of the Chicago Pizza rounded to the nearest cent.

A. $0.07 per square inch

B. $0.02 per square inch

C. $0.24 per square inch

D. $0.08 per square inch

A. $0.07 per square inch

Step-by-step explanation:

Chicago Pizza has a diameter of 14".

radius = diameter/2 = 7"

area = (pi)r^2 = 3.14159(7 in.)^2 = 3.14159(49 in.^2) = 153.934 in.^2

cost per sq inch = ($10.49)/(153.934 in.^2) = $0.068 per square inch

A. $0.07 per square inch

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
