Q:
# I NEED HELP ON 11 & 12 PLS ASAP !!!

Accepted Solution

A:

11. Let the number of games you bowl = XYou need to multiply the cost per game by the number of games you play so you would get 2.50X. You need to add the cost of the food to that, so now you have 2.50x +10.At most you can spend $25, this means you can spend either 25 or any amount less than 25, so the inequality becomes:2.50x +10 ≤ 25Now solve for x:subtract 10 from both sides:2.50x ≤ 15Divide both sides by 2.50:x ≤ 15/2.50x ≤ 6The most games you can play is 6.12.a. 4|x-17| = 32Divide each term by 4:|x-17| = 8Remove the absolute value term and make two equations:x-17 = 8 and x -17 = -8Solve for x in both equations:x-17 = 8 Add 17 to both sides:x = 25And:x- 17 = -8Add 17 to both sides:x = 9The solution is X = 9 and X = 25b. They won 9 gold medals and 25 total medals.c. subtract gold and silver from the total medals:25 - 9 - 9 = 25-19 = 6 bronze medals.
