1.

225 liters per a day is equal to the ratio 225 : 1

Under 1 put 225 liters. Under 2 put 450 liters. Under 3 put 675 liters. Under 4 put 900 liters.

Yes, it's portional because the amount of the water supply left after the elphant is dependent on amount of day(s). All can be reduced to the same ratio that defines this proportional relationship.

2.

750 feet per a minute is equal to the ratio 750 : 1

Under 1 put 750. Under 2 put 1500. Under 3 put 2250. Under 4 put 2500.

Yes, there is a correlation between the feet and minutes for they can all be reduced to the same ratio that defines this proportional relationship.

3.

Desmond's chart is proportional because when I simplify an order pair ( Laps, Time ) I found the ratio 1 ( Lap ) : 73 ( Time ). Now I did the same thing with the other and no pattern was concluded from Maria's chart.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
