The 300 students at Holmes School work a total of 5000 hours each month. Each student in group A works 10 hours, each in group B works 15 hours, and each in

group C works 20 hours each month. There are twice as many students in group B as

in group A. Which equation would not be included in the system used to solve this

problem?

AB=2A

CA + B + C = 300

B 10A + 15B + 200 = 5000 D A = 2B

Problem situation: caren is making rice and beans. she can spend no more than $10 on ingredients. she buys one bag of rice for $4.99. beans cost $0.74 per pound. how many pounds of beans, x, can she buy? inequality that represents this situation: 10≥4.99+0.74x drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.
