Consider a chessboard, which has a total of 64 squares. one grain of rice is placed on the 1st square, 2 grains on the 2nd square, 4 grains on the 3rd square, 8 grains on the 4th square, and so on. how many grains of rice will be placed on square number 18?

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.
