Question

1 Ms. Kwan is making sandwiches for a class picnic. She prepares 1 1/2 Sandwiches for each student in the class and 4 more sandwiches in case there are guests. Which inequality shows how many students, s, are in the class if Ms. Kwan prepares no fewer than 49 sandwiches? A)s>30 B)s _> C)S<30 D)s_<30

Answer 1

Answer: S ≤ 30

Explanation:

First: 49- 4 = 45

Then: 1 1/2 ≤ 45

Next: Divide both by 1 1/2 to get the answer S≤ 30

Answer 2

Since we know that Ms. Kwan made 4 more sandwiches in case there are guests, she made
`49-4=45` sandwiches for he students.
We also know that she made
`1 (1)/(2)` for each student, so to find we many sandwiches she made for her students, we are going to divide 45 by
`1 (1)/(2)`:

`(45)/(1 (1)/(2) ) = (45)/(1.5) =30`

We can conclude that since she made 30 sandwiches for her students, there are no more than 30 students in her class, or in mathematical notation:
`s \leq 30`.
