Step-by-step explanation:
The way to approach the problem is this
After one year she has 2000*1.05
After two years she has the money from the last year plus interest, so she has 2000*1.05*1.05
After t years she has 2000*1.05
Amigo eso es Salchicha no entiendo como ayudarle con esa tarea perdón
(8x n) + 15=7 : 7-15= (-8), (-8)divided by 8= (-1) : n=(-1) : When you have problems like this it helps to work them backwards. Hope you understand this.
P/L=4/7 and P=L-12 so
(L-12)/L=4/7 multiply both sides by 7
(7L-84)/L=4 multiply both sides by L
7L-84=4L subtract 4L from both sides
3L-84=0 add 84 to both sides
3L=84 divide both sides by 3
L=28, and since P=L-12
P=16
So they had 28+16 = £44 in total.
