For a field trip the school bought 39 sandwiches for 4.35 each and 42 bags of chips for 15 cent each how much did the school spend in all

1 sandwich : 4.35

1 chips : 0.15

Total spending:

39 sandwiches + 42 chips = (39*4.35) + (42*0.15) = 175.95

Step-by-step explanation:

For a field trip, the school bought 39 sandwiches and 42 bags of chips. Each sandwich cost 4.35. That means the cost of 39 sandwiches would be

39 * 4.35 = 169.65

Each bag of chip costs 15 cents. Converting 15 cents to dollars, it becomes

15/100 = $ 0.15

Therefore, the cost of 42 bags of chips would be

42 * 0.15 = 6.3

Total cost of 39 sandwiches and 42 bags of chips would be

169.65 + 6.3 = 175.95
