Which is a better deal a 16in diameter pizza for$12.99 or an 8in diameter pizza for $6?

To answer this question, find the unit rates for price per pizza. You can do this by simply dividing the diameter (which is directly proportional to the area of the circle) by the price:

The 8in pizza has a greater cost per unit, and is therefore lesser of a value. Your answer is the 16in pizza for $12.99 because it has a cost per unit of $1.23.

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!
