Answer:
$0.80 per notebook
$0.40 per pencil
Step-by-step explanation:
To find the rate, we need to determine how much each item costs. That is, the cost per item.
Given that,
4 notebooks = $3.20
The cost of 1 notebook/rate =
Rate = $0.80 per notebook
Given that,
12 pencils = $4.80
The cost of 1 notebook/rate =
Rate = $0.40 per pencil.
Answer:
7.65 meters.
Step-by-step explanation:
Let x represent the distance that diver will travel.
We have been given that a scuba diver is exploring at an elevation of -12.2 meters. As the diver rises to the surface, she plans to stop and rest briefly at a reef that has an elevation of -4.55 meters. We are asked to find the distance that diver will travel.
The initial elevation plus x will be equal to -4.55 meters. We can represent our given information in an equation as:
Therefore, the scuba diver will travel a vertical distance of 7.65 meters.
