Profit = 0.25x + 0.20y
Step-by-step explanation:
cost price of 1 pencil = RM 0.60
So, C. P. of x pencils = 0.60x
Similarly,
C. P. of y erasers = 0.40y
Total C. P. = 0.60x + 0.40y
Selling Price of x pencils = 0.85x
S. P. of y erasers = 0.60y
Total S. P. = 0.85x + 0.60y
Profit = Total S. P. - Total C. P.
= (0. 85x + 0.60y) - (0.60x + 0.40y)
= 0. 85x + 0.60y - 0.60x - 0.40y
= 0.85x - 0.60x + 0.60y - 0.40y
Profit = 0.25x + 0.20y
