Answer:
The change received by Judy is $ 2.69.
Step-by-step explanation:
Bill paid = $ 10
Cost of binder = $ 1.38
Cost of pack of pencils = $ 2.05
Cost of box of erasers = $ 3.88
Total cost of the school supplies = $ 1.38 + $ 2.05 + $ 3.88 = $ 7.31
The amount of change Judy received = $ 10 - $ 7.31 = $ 2.69
The answer would be D. 7 weeks, $230.
Explanation: y would be the total amount after x weeks. So, to find the answer, simply go through your choices and insert x and y. Both y's for Joy and Cullen have to match up for the answer to be correct.
For answer D, it looks like:
Joy: 30(7) + 20 = 230
Cullen: 20(7) + 90 = 230
A unit multiplier is a conversion factor of value 1 that we can use to convert quantities.
We want to convert 123 pounds per mile to ounces per centimeter.
First, we are going to express the quantity to convert as a fraction:
123 pounds per mile=
Next, we are going to find our multipliers:
- We know for our problem that there are 5,280 feet in 1 mile, so our first multiplier will be:
- We also know that there are 16 ounces in 1 pound, so our second multiplier will be:
- We know that there are 12 inches in 1 foot, so our third multiplier will be:
- We know that t<span>here are approximately 2.54 cm in 1 inch, so our fourth multiplier will be: </span>
Now we can put all our multipliers together:
We can conclude that the answer is
0.01
X+3x+5x=27
x=27/9=3
