A) I cannot really put a graph here but it should be something like 6x+7.5y> or = 75, x+y < or = 15
B)Choice 1 and 3
Step-by-step explanation:
For part A we can say that x is how many hours he walks his neighbor's dogs and y for how many hours he washed cars and set up equation so that he gets more than 75 dollars and less than 15 total hours. For part B, the last choice can be eliminated because it exceeds total of 15 hours, choice 2 can be eliminated because it does not reach a 75 dollars if you use the value of x and y in the equation in part A, therefore answers are choice 1 and 3.
Since he has a 4-gallon aquarium and a 1-quart container, and since there are 4 quarts in every gallon, he'll need to fill the aquarium with the container full 16 times because for every gallon, he'll need to fill the aquarium 4 times. This is the equation:
