Q. Jimmy wants to ship some dumbbells to his sister. The flat rate box he is using allows a maximum weight of 7070 pounds. Which of the following inequalities describes x x , the number of 1010 -pound dumbbells, and y y , the number of 1515 -pound dumbbells, Jimmy can send in the flat rate box?\newlineChoose 11 answer:\newline(A) 10x+15y≤70 10 x+15 y \leq 70 \newline(B) 15x+10y≤70 15 x+10 y \leq 70 \newline(C) (x+10)+(y+15)≤7 (x+10)+(y+15) \leq 7 \newline(D) (10+15)(x+y)≤70 (10+15)(x+y) \leq 70
  1. Identify variables and weights: Identify the variables and their corresponding weights. We have xx representing the number of 1010-pound dumbbells and yy representing the number of 1515-pound dumbbells. The weight of the dumbbells sent by Jimmy is the sum of the weights of the 1010-pound and 1515-pound dumbbells.
  2. Write total weight inequality: Write the inequality that represents the total weight of the dumbbells. The total weight is 10x10x for the 1010-pound dumbbells plus 15y15y for the 1515-pound dumbbells. This total weight must be less than or equal to the maximum weight allowed by the flat rate box, which is 7070 pounds. So, the inequality is 10x+15y≤7010x + 15y \leq 70.
