The graph shows the amount of money paid when purchasing bags of caramel corn at the zoo:
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 9. These points are joined by a line. The label on the x-axis is Bags of caramel corn. The title on the y-axis is Total cost in dollars.
What does the point (0, 0) on the graph represent? (4 points)
The cost of zero bags of caramel corn
The cost of one bag of caramel corn
The cost of two bags of caramel corn
The cost of three bags of caramel corn
The point (0, 0) on the graph represents the cost of zero bags of caramel corn.

The table below shows the amounts of cherry juice and soda used in each container of cherry soda. The ratio of cherry juice to soda is 1:r, where r is the unit rate. Use the table to determine r.
Cherry Juice (cup) Soda (cup)
one-fourth 1
2 8
3 12
one-fourth
4
2
two-thirds
To find the unit rate (r), we need to find the ratio of cherry juice to soda in each case.
In the first case, the ratio is 1:4 (one-fourth cup cherry juice to 1 cup of soda).
In the second case, the ratio is 2:8 (2 cups cherry juice to 8 cups of soda).
In the third case, the ratio is 3:12 (3 cups cherry juice to 12 cups of soda).
We can simplify these ratios to their lowest terms:
1:4 can be simplified to 1:4
2:8 can be simplified to 1:4
3:12 can be simplified to 1:4
In all three cases, the ratio of cherry juice to soda is 1:4. Therefore, the unit rate (r) is 4.
Which unit rate is equivalent to 13 miles per gallon?
twenty-six miles over two gallons
two gallons over twenty-six miles
thirty-nine miles over four gallons
four gallons over thirty-nine miles
The unit rate equivalent to 13 miles per gallon is thirty-nine miles over four gallons.
The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate their unit rate in miles per hour? (5 points)
three-fifths over three-eights equals one and three-fifths miles per hour
three-eighths over three-fifths equals one and three-fifths miles per hour
three-eighths over three-fifths equals five over eight mile per hour
three-fifths over three-eights equals five over eight mile per hour
The equation that can be used to calculate their unit rate in miles per hour is:
(three-fifths) / (three-eighths) = (five over eight) miles per hour
So the correct answer is: three-fifths over three-eighths equals five over eight mile per hour.
