So you divide 2.19 by 18 and you get .12  so it cost 12 cents per ounce
then you divide 4.39 by 48 and you get .09 so it cost 9 cents per ounce

So it would be better idea to but the 48 ounce jar because it costs less oer ounce of peanut butter

2.19/18 = 0.12167 per ounce
4.39/48 = 0.09 per ounce

the larger jar is the better buy

Sheila is baking a few cakes for the bake sale for her school. Each cake requires 2 ½ cups of sugar. How many cakes can she bake
Ber [7]

Answer:

The answer is 2 cakes.

Step-by-step explanation:

What we know:

-Each cake requires 2 1/2 cups of sugar.

-Sheila has 7 1/3 cups of sugar.

What we need to know:

-How many cakes can Sheila make with 7 1/3 cups of sugar.

Remember:

-You must make a whole cake.

Show your work:

-I am going to convert the fraction into a decimal.

-2 1/2=2.5 and 7 1/3=7.3

-2 cakes will require 5 cups of sugar and you will remain with 2.3 cups of sugar.

-You <em>cannot </em>use 2.3 cups of sugar to make a cake. It must be in full.

What is thirty percent of two hundred ?
shtirl [24]

The answer is 60. Because if u do 30% x by 200 but u need to get rid of the percent which means u divide it by 100 to get rid of a percent and multiply by a hundred to get a percentage. So it would be 30 x 200 divided by 100.
