<span>(A) formulate an equation for x: A$100= S$(65-5) So A$100= S$(60) So A($100)/60 = S$(60)/60 THEN A(1.66)= S$(1) (B) find the value of x: (By the previous equation provided x = ((A$100)/(S$))+5 (C) find the amount of Singapore dollars mr neo received if he exchanged A$125 in November 2013: IF A$(1.66)=S$(1) then A$(1.66x125)= S$(207.50) Thank you!</span>
You see I need to know also the reproduction rate as well to equalize it. If 9% of the population declines each year from 2001 to 2021, around 21,006 would die by 2021. Which is 180% more than the population. If the reproduction rate isn't high enough to beat the declination rates, they'd be extinct by then.
It would be 525.50*0.06=31.53
And the total would be 525.50+31.53=557.03
Hope this helps
Part a: the first cereal is y=7x and the second one is y=10x so they are $3 apart.
part b: y=7*4 (28) and y=10*4 (40) is $12 apart so she will save $12 each month.
