Step-by-step explanation:

Decimal pt after 3 digits in first number so 3 digits in product.
I believe this is the right way to write the function
N = [log A − log P] / log(1.0175)
N =[ log (1210.26) - log (1000)]/log (1.0175)
N =log [1210.26/1000] / log (1.0175) = log (1.21026)/log(1.0175) = 0.08288/0.00753 = 11
N = 11 months
Terriers = x
Labs = 5x
5x + x = 18
6x = 18
6x / 6 = 18/6
x = 3
There are 3 Terriers
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.
