Question

Alexandra has $15 to buy drinks for her friends at the baseball game. Soda costs $2.75 and bottled water costs $2.00. This relationship can be represented by the inequality 2.75s+2w

Answer 1

`2.75s+2w\leq 15`

Explanation:

Let

s-------> the number of sodas

w-----> the number of bottled water

we know that

The inequality that represent the situation is equal to

`2.75s+2w\leq 15`

using a graphing tool

The solution is triangular shaded area

see the attached figure

The domain (number of sodas) is all positive whole numbers belong to the interval [0,1,2,3,4,5]

The range (number of bottled water) is all positive whole numbers belong to the interval [0,1,2,3,4,5,6,7]
