Use the following problem statement to answer questions 1-3. A bicycle Company has been making bicycles for almost 30 years. There are four models in the company's line. The company only focuses on producing bicycles ranging from 20-inch models to 26 -inch models. Most of their sales were through retail stores such as Walmart. Each week it must produce at least 400 girl models and 300 boy models. Table 1 shows the unit profit and the number of minutes required for production for each model. Table 1 The production team runs two (eight-hour) shifts per day, five days per week. This week, there are 900 tires available for the 20 -inch models and 800 tires available for the 26 -inch models, which were designed to significantly reduce expenses associated with the replacement and maintenance of tiers. Each bicycle requires two tires. The company wants to maximize total profit. Develop a model to determine the number of bicycles to produce. [Note: X1= no. of 20 -inch girl bicycles; X2 = no. of 20-inch boy bicycles; X3 = no. of 26-inch girl bicycles; X4 =no. of 26 -inch boy bicycles.] Which of the following constraints is correct? x1+x4400x2+x3=400x1+x3400 Which of the following constraints is correct? 121+122+93+9480121+122+93+94480081+82+123+1244800 Question 3 Which of the following constraints is correct? 22+2390023+2490021+22900
