In the given problem, apply your knowledge in algebraic and basic mathematics specially solving word problems involving linear equation.

Given:

earns a commission of P80.00 for each oven

P50.00 for each electric fan

P3000.00 or more in commissions

Solution:

Let x stands for the number of oven she sells, and y for electric fan

Total Commission = 80(x) + 50(y)

3000 = 80(x) + 50(y)

Simplify

3000 = 80(x) + 50(y)

1/10[3000] = 1/10[80(x) + 50(y)]

300 = 8x + 5y

3000 or more means greater than or equal to 3000

8x + 5y ≥ 300

5y ≥ 300 - 8x

y ≥ 60 - 1.6x

Set values for x to get the value of y.

If x = 10, y ≥ 60-1.6(10) → y ≥ 44

Answer:

If she sells 10 oven, she must sell 44 or more electric fan.
