Aiko works in the fish department of a pet store. She is asked to drain, clean, and refill two reef tanks. The first tank holds 175 gallons of water, and the second tank holds 200 gallons of water. The hoses that she
uses drain the tanks at a rate of 25 gallons of water per hour.
1. Write an equation for each tank that represents the total amount of water in gallons in the tank, y, in
terms of the number of hours, x, that the tanks are draining.
2. How much water is in each tank after 3 hours?
3. Write your equations in the first row of the table. Then, complete the table of values for the linear system.

the answer i think is a)

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
