Martin’s grandma gave him a $100 gift certificate to his favorite restaurant. Everyday for four days Martin went to the restaurant and bought a drink for $1.19 and fries for f dollars. Write an expression for how much money Martin has left on his gift certificate.
Ans = 95.24 - 4f
1day = $1.19 + f
4days = 4(1.19 + f) = 4.76 + 4f
Left = 100 -(4.76 + 4f) = 95.24 - 4f

Juab Junior High School wants to meet its goal of reading 10,000 books in three months. If 7th grade reads x number of books every week, 8th grade reads y number of books every week, and 9th grade reads z number of books every week, write an expression for how many books the school will still need to read after 3 weeks?
Ans: 10000 - 3x -3y -3z or 10000 - 3(x + y + z)
7: x books per week; 8 = y books per week, 9 = z books per week
1 week books = x + y + z
3 weeks = 3(x + y + z) = (3x +3y + 3z)
