Problema Solution
3. Stella’s Sea Food Shop only sells sardines ($8 per serving) and salmon snacks ($12 per serving). In June, Stella’s sold 900 servings altogether, and their total sales were $9,600. How many servings of each did Stella’s sell?
Answer provided by our tutors
let
x = the number of sardine servings
y = the number of salmon snack servings
Stella’s sold 900 servings altogether:
x + y = 900
and their total sales were $9,600:
8x + 12y = 9600
by solving the system of equations:
x + y = 900
8x + 12y = 9600
we find:
x = 300 sardine servings
y = 600 salmon snacks servings
