please solve part B with lingo programm

Question 1 Toolce has contract with Automate to supply their automotive discount stores with wrenches and chisels. Automate weekly demand consists of 1500 chisels and 1200 wrenches. Toolca's present oneshift capacity is not large enough to produce the requested units and must use overtime and possibly subcontracting with other tool shops. The result is an increase in the production cost per unit, as shown in the following table. The market restricts wrenches to chisels to a ratio of at least 1:2. (a) Formulate LP for the minimization of the system costs (b) Assume the variables are to be integer, solve the model using Lingo
