Question

Does anyone know how to do this I’m really lost

Answer 1

See explanation

Explanation:

Let

x = number of hotdogs purchased

y = number of drinks purchased.

1. The restaurant sells hotdogs for $3.50 each, so x hotdogs cost $3.50x and drinks for $1.75 each, so y drinks cost $1.75y.

Isabella has $35 to spend, so

`3.50x+1.75y\le 35`

2. Isabella must buy no less than 13 hotdogs and drinks altogether, so

`x+y\ge 13`

3. Plot both inequalities on the coordinate plane. The common region (region where two shaded regions intersect) is the solution to the system of two inequalities.
