Suppose the wages of the cafeteria workers on campus increase by 10% forcing the price of meals to increase at the same time your scholarship income doubles. (cafeteria meals are an inferior good.) how will these changes impact the quantity and price levels in the cafeteria food market? quantity / price increase / indeterminate increase / decrease decrease / indeterminate decrease / increase indeterminate / decrease

The correct answer is:  [C]:  "decrease / indeterminate" .

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

How are we suppose to know this
