Answer:
The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.
Step-by-step explanation:
It is given 4 dozen pairs of gloves for $56.16.
So, unit price = Divide the price by number of pairs of gloves.
And 1 dozen =12
So 4 dozen =4*12=48 pairs of gloves
So, to find unit rate divide 56.16 by 48.
Unit price =
So, the error is she didn't convert the dozen to units.
That made mistake in finding unit price.
Answer:
x=2
Step-by-step explanation:
Here what we need is that the ratios be equal, which is:
x:(5/2) = 8:10 or, what is the same:
x/(5/2) = 8/10
Lets pick the left term x/(5/2) and multiply both numerator and denominator by 2 to eliminate the fraction on the denominator:
2x/2(5/2) = 2x/5
Now, we would like to make a 10 appear on the denominator. As we already have a five we need to multiply numerator and denominator by the num that, multiplied by 5 gives as 10, this is 2:
2(2x)/2(5) = 4x / 10
So, we transformed x/(5/2) in 4x/10, and both are the same, so we can replace it on our first equation:
4x/10 = 8/10
As both denominators are equal, we can concentrate only in numerators:
4x = 8
Dividing both sides by 4:
x = 2
So, for x=2 both ratios are equivalents.
I think c would be the correct answer
The first one is the answer/
All you have to do is multiply both
