28/21
Step-by-step explanation:
You would do y1 - y2 for the numerator which gets you 28. Then you would do x1 - x2 for the denominator which gets you 21. The rate of change is also the slope.
Hope this helps!
Total = Principal * (1 + (rate/n))^n*years
where n is the number of compounding periods per year
Total = 12,500 * (1 + (.0275/4) )^40
Total = 12,500 * <span>(1.006875) ^40

The present age of the mother is 30 years.
<u>Step-by-step explanation</u>:
Step 1 :
At present,
- Age of Jane = x
- Age of Billy = 5x
- Age of mother = 3(5x) = 15x
Step 3 :
After 2 years,
- Age of Jane = x+2
- Age of mother = 8 times as Jane = 8(x+2)
Step 3 :
Age of mother at present + 2 years = Age of mother after 2 years
⇒ 15x + 2 = 8(x+2)
⇒ 15x + 2 = 8x + 16
⇒ 7x = 14
⇒ x = 2
Step 4 :
Substitute x=2,
Age of mother at present = 15x = 30 years.
