Question

Use vector operations like element-by-element multiplication and the sum command so that your program would work with any number of bedroom set types. A discount furniture store sells four types of bedroom sets. The cost (in dollars) of each set can be represented by the array Cs = [ 199, 2 68 , 500, 670] . The price at which the store sells each set can be represented by the array Ps = [ 398 , 598, 798, 998]·in a particular quarter the number of sets sold of each type can be represented by the array Ns = [ 35, 25, 20 , 10], write a program, furniture.m, that calculates and reports: a. b. c.
