Can you help me solve the question? Thank you!

Q4. Professor Can gets a plate of lasagna and a coke every night for dinner from one of the many restaurants in Richardson. He picks the restaurant at random and independently of previous days. The average price of a plate of lasagna is $14 with a standard deviation of $3, the average price of a coke is $2.50 with a standard deviation of 154, and the two prices are independent of each other. What is the mean and standard deviation of the amount Can spends on dinner weekly (7 days)? (1.5 points)
