Zhao xue wants to buy milk and yogurt. she wants to buy a total of at least 6.5 gallons of dairy products (condition a), and she has a budget of $20 (condition b). the graph represents the constraints on the number of gallons of milk m and yogurt y zhao xue buys. zhao xue buys 4 gallons of milk. how many gallons of yogurt can she buy to meet both her constraints? a.) exactly 2.5 gallons b.) at least 4 gallons and at most 6.5 gallons c.) at least 2.5 gallons and at most 4 gallons d.) zhao xue doesn’t have enough money left to buy any yofurt

The answer is (D). Zhao Xue doesn’t have enough money left to buy any yofurt

Step-by-step explanation:  Given that Zhao Xue is buying buy milk and yogurt, a total of at least 6.5 gallons of dairy products and she has a budget of $20. The given graph represents the constraints on the number of gallons of milk 'M' and yogurt 'Y' Zhao Xue buys. Zhao Xue buys 4 gallons of milk. We need to calculate the number of gallons of yogurt she can buy to meet both her constraints.

From the graph, we can write

Condition A :

Condition B :

Now, if she buys 4 gallons of milk, the the conditions become

Here, there will be no solution to these constraints.

Therefore, she does not have enough money left to buy any yogurt.

Thus, the correct option is (D).

step-by-step explanation:

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
