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.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
