A consumer has a budget of $3000 in a given period, and wishes to buy two goods, X and Y, so as to maximise his utility. The price of good X is $5 and the price of good Y is $2, and his MRS is given by the formula 2Y/X. How many units of good X will he buy in that period?

A woodworking artist makes two types of carvings: type X and type Y. He spends 3 hours making each type X carving and 2 hours making each type Y carving, and he can spend up to 30 hours each week making carvings. His materials cost him $5 for each type X carving and $7 for each type Y carving, and he must keep his weekly cost for materials to $105 or less. If x is the number of type X carvings he makes in a week and y is the number of type Y carvings he makes in a week, which of the following systems of inequalities models this situation?A.3x + 2y ≥ 30, 5x + 7y ≥ 105B.3x + 2y ≥ 30, 5x + 7y ≤ 105C.3x + 2y ≤ 30, 5x + 7y ≤ 105D.3x + 2y ≤ 30, 5x + 7y ≥ 105SUBMITarrow_backPREVIOUS

Mitul is buying snacks for the student council meeting. She wants to buy 400 cookies. Cookies are available at a store in two different sizes of packages: small (S) and large (L). There are only 6 large packages left at the store and Mitul can spend a maximum of $60 on cookies. The table below shows the number of cookies and the cost of the two package sizes.Which system of inequalities represents this situation?24S + 36L ≥ 4003S + 5L ≥ 60L ≤ 6 24S + 36L ≤ 4003S + 5L ≤ 60L ≤ 6 24S + 36L ≥ 4003S + 5L ≤ 60L ≤ 6 24S + 36L ≤ 4003S + 5L ≥ 60L ≥ 6
