Julia’s Food Booth Based on the LP model to maximize profit with the established constraints Julia should sell pizza and hotdogs and not BBQ sandwiches. Based on this model Julia will earn $2250.00 in profit. After buying food supplies for the next game she will have $750 remaining ($2250-1500). Julia’s goal was to clear $1000 in profit which she was not able to meet. It is not clear how Julia is paying for the booth rental each game‚ but assuming she is covering the costs with her profits from

MA1506 TUTORIAL 1 1. Solve the following differential equations: (a) x(x + 1)y = 1 (b) (sec(x))y = cos(5x) (c) y = e(x−3y) (d) (1 + y)y + (1 − 2x)y 2 = 0 Use www.graphmatica.com to sketch the functions you found as solutions of [a]-[d]‚ if y = 1/2 at x = 1. Graphmatica can also directly sketch the graph if you insert the equation itself; for example‚ in [a] you just enter x(x + 1)dy = 1 {1‚ 1/2}.
