Question

30. Ms. Jacobs has $15.00 to spend on coffee and donuts. She buys 1 coffee for $2.59. The cost of each donut is $1.09. Which inequality could be used to determine the greatest number of donuts, d, that Ms. Jacobs can buy? A 1.09d+2.59 ≤ 15 B 1.09d+2.59 ≥ 15 C 1.09+2.59d ≤ 15 D 1.09 +2.59d ≥ 15​

Answer 1

The inequality that could be used to determine the greatest number of donuts, d, that Ms. Jacobs can buy is 1.09d+2.59 ≤ 15, which is option A.

Step-by-step explanation:

The inequality that could be used to determine the greatest number of donuts, d, that Ms. Jacobs can buy is 1.09d+2.59 ≤ 15, which is option A.

To determine the greatest number of donuts, we need to find the maximum quantity of donuts that Ms. Jacobs can buy while staying within her budget of $15.00. The cost of 1 donut is $1.09, so the cost of d donuts would be 1.09d. Since she also buys 1 coffee for $2.59, the total cost of the coffee and donuts should be less than or equal to $15.00.

Therefore, the correct inequality is 1.09d+2.59 ≤ 15 (option A).
