z= (x- )/

z= 20000/4000
z=5.

In this math problem, we will be using rate of change.
850 naira’s / 20 mangoes 
= 42.5 nairas for one mango.
Next, to find the cost of 15 mangoes, we will take the cost of our one mango and simply multiply it by 15.
= 42.5 nairas * 15
= 637.50 nairas
So, in conclusion, the cost of 15 mangoes is 637.50 naira.
