You would write the expression as nP +nL=cost because it’s the number of plagues that he buys plus the number of loaches that he buys
Answer:
Total cost = XP+XY
Step-by-step explanation:
Let x represent the unit cost of Platies (P)
Y represent the unit cost of loaches (L)
Cost of Platies = P * X = XP
Cost of Loaches = L * Y = LY
Total cost = XP + LY
