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

Answer:
See explanation
Step-by-step 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
[tex]3.50x+1.75y\le 35[/tex]
2. Isabella must buy no less than 13 hotdogs and drinks altogether, so
[tex]x+y\ge 13[/tex]
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.
