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.)
