Finite mathematics 1st year college homework help
Hi I'm struggling with two questions and would love some help.
1. Brian requires 2100 calories per day to maintain his daily activities and to maintain a constant weight. He wants to gain weight. Each pound of body weight requires an additional 3300 calories. Write his daily calorie intake as a linear function of the number of pounds gained per day. (Let y represent the caloric intake and x represent the number of pounds gained.)
2. The U.S. Department of Education estimated that the average annual cost (tuition, fees, room, and board) of attending a four-year private college or university was $21,855 in 2000 and $31,704 in 2008.
(a) Find the cost as a linear function of time since 2000. (Let y represent annual cost and x represent the year with
x = 0 representing 2000. Round the slope to the nearest whole number.)
y = _______
(b) Use the linear function to estimate the cost in 2015. (Round your answer to the nearest whole number.)
