Sagot :
Answer:
6 bags of snack mix
Step-by-step explanation:
x bags of snack mix
y bottles of water
The equations in the question is given as;
20.00 = 2.50x + 1.00y (i)
11 = x + y (ii)
From eqn (ii);
11 - y = x
substitute the value of x in eqn (i);
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = - 1.50 y
- 7.5 = - 1.50 y
y = - 7.5 / (- 1.5) = 5
Since we are interested in the value of x. Substitute the value of y in eqn (ii);
11 = x + 5
x = 11 - 5 = 6
