Mr. Saleh is one of the school canteen operators who joined The Supplementary Food Plan (RMT) organized by the Ministry of Education Malaysia. Assuming that each RMT student has been allocated RM3-RM4 for his meal per day. Due to that, Mr. Saleh needs to prepare one meal set consisting of one chicken rice and a box of milk for each RMT student. The raw cost of one week of meal preparation for 20 RMT students is as much as RM330 while for 100 RMT students are RM1650. The cost of chicken rice is twice the cost of the milk. Write simultaneous equations for the above situation. а. b. With the substitution method, determine the cost for chicken rice. с. With the elimination method, find the cost of each milk. d. Determine the raw cost of each RMT meal. Calculate the maximum number of RMT students that can be allocated if the weekly budget is RM2500. е.
The workers of the company "Malova" work in a 5-day work week and worked them for 22 days in the month of November 2020. The standard work schedule is 8 hours per day with a 30-minute break included in this time. Now, "Malova's" company is in the process of manufacturing screwdrivers and manufactured 3100 pieces of screwdrivers. In addition, the company manufactures screwdrivers in batches of 300 and after each batch makes a pause to check the quality of production and make certain adjustments to the machines if necessary. The break is 1 hour. Calculate the parts produced per hour by the Malova company in November. Important: Use the formula (the one I put in the image)
