You discover that you are over serving a dish because customers keep taking a third of it home. If the dish requires 4 ingredients with 3 parts each to prepare for a total of 12 parts, how many parts would you need to subtract to reduce the dish to two-thirds its current size?
If the total number of parts is 12 and you want to reduce the dish to two-thirds its current size, the number of parts that will be reduced is (1 - 2/3) = 1/3
To reduce 1/3 of the 12 parts, you need to multiply 12 by 1/3 to know how many parts is that:
12 * 1/3 = 12/3 = 4
You need to subtract 4 parts. If you have 4 ingredients, you can remove 1 part of each, so each ingredient now will have 2 parts.
The pasta plate will cost $ 5.5
y=4x+2.5 ( x is the number of ingredients)
$ 2.5+(4*0.75)= 5.5 dollars
8 pineapples = 8 mangoes
8 mangoes x 4 apples = 32 apples
32 apples x 2 pears = 64 pears
