Save-way-more food store received a delivery of 86 boxes of apples and bananas. Each box of apples had a mass of 32 Ib., and each box of bananas had a mass of 16 Ib. The total mass of the delivery was 1968 Ib. a.) Write a linear system to model this situation. b.) How many boxes of each fruit were there? Graph, indicate your solution clearly and give the windows on your calculator.
1) write a linear system - let a = boxes of apples and b = boxes of bananas a + b = 86 32a + 16b = 1968 2) solve - use substitution a = 86 - b 32(86 - b) + 16b = 1968 2752 - 32b + 16b = 1968 -16b = -784 16b = 784 b = 49 a + 49 = 86 a = 37 37 boxes of apples and 49 boxes of bananas
