It depends on what you are trying to find if you are trying to find the unit rate for oz/dollar or dollar/oz it differs. But, for the second option it is $0.14 dollars. For the first it is 7.32 oz per dollar. I assume you are trying to find dollar/oz because it makes more sense.
Hope this helps explain what was needed to be solved! :)
Answer:
The percent of pages Jace read at school is × 100 = 15%
The percent of pages Jace need to read at home is 100% - 15% = 85%
Step-by-step explanation:
Scale 1: One division represents 100% ÷ 20 divisions = 5%
Scale 2: One division represents 20 pages ÷ 20 divisions = 1 page
The proportion that can be used to determine the percentage of pages Jace read at school is 3 out 20 pages =
Jace need to read 20 - = pages at home.
That is × 100 = 85%
I believe the correct answer is 6.3
