Answer:The percent decrease was 15%
Step-by-step explanation:
In order to find this, use the percent change equation.
(New - Old)/(Old) * 100 = % Change
Now input 149.42 for the New price and 175.80 for the Old price.
(149.42 - 175.80)/(175.80) * 100 = % Change
-26.38/175.80 * 100 = % Change
-.15 * 100 = % Change
-15 = % Change
Step-by-step explanation:
The rate that is not equivalent to the others is "1 for $0.75".
<h3>
How to find the rates?</h3>
To find the rates, you need to take the quotient between the price and the number of units, these rates, give the value of a single item in dollars.
Here, the four rates are:
- 1) $36/27 = $1.33...
- 2) $4/3 = $1.33...
- 3) $20/15 = $1.33...
- 4) $0.75/1 = $0.75
So we can see that the rate which is not equivalent to the others is the last one (the bottom right one).

Answer:

Step-by-step explanation:
Answer:
one is equal
Step-by-step explanation:
this is asking which 2 paired items have the same fractional ratio I believe. So all we have to do is make ratios of price to item amount and see if they are equal.
1. 4.5/3 = 6/5
this one we divide numerator and denominator of left side by 1.5 and get:
3/2 = 6/5
this is not true so wrong
2. 5/2 = 15.25/6
2.5 = 2.5416666
sometimes easier to use calculator then reduce. But not equal so wrong.
3. 4.75/5 = 9/10
95/100 = 9/10
wrong
4. 9/4 = 13.5/ 6
4.5/2 =4.5/2
this one is equal
