Taylor purchased three types of items (bags of candy, picture frames, and some packs of stickers) from a store. the bags of candy are $1, the picture frames are $2, and the packs of stickers are $3. taylor spent a total of $16 on 9 items, and purchased three times as many bags of candy as she did packs of stickers. how many of each item did she purchase?

if x = the number of bags of candy, y = the number of picture frames, and z = the number of packs of stickers, which equation is not needed to model this situation?
a) x = 3z
b) z = 3x
c) z = x3
d) x + y + z = 9

D

Step-by-step explanation:

To write an expression and equation, define the variables.

Taylor purchased three types of items:

x = number of bags of candy

y = number of picture frames

z = number of stickers.

We know she bought 9 items.

So x+y+z = 9.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

you already gave the answer
