Question

Dakota's wife sends him to the store to buy pickles and ice cream. Ice cream cost 8 dollars per pound and pickles costs 5 dollars per pound. Dakota has 40 dollars in his wallet. Let x be the number of pounds of ice cream and y be the number of pounds of pickles that Dakota purchases. State the inequality that represents his budget, and graph the solution that represents the possible combinations of x and y . Express your answer with the standard form a x + b y on the left side. The budget inequality is _______

Answer 1

8(3)+5(3)=40

Explanation:

Start with 8(x)+5(y)=40

Next note that if you times them by each other you get 40

now knowing you can't have it over 5 for either helps you know you shouldn't have more than 4 either

knowing that 3 is the best option for both

If you not that 8 and 5 are both not prime you can get 40 exactly

Answer 2

8x + 5y ≤ 40

Step-by-step explanation:

x = amount of ice cream($8 each)

y = amount of pickles($5 each)

8x + 5y ≤ 40

It has to be ≤ 40 because the dude only has $40 and can't exceed that.
