Well, we can use some simple addition, okay? So if Ally has 7 cubes, and Greg has four, we can use the equation: x+y = ?, so 7 + 4 = 11. x and y don't mean anything in this scenario, but I just used them as variables. I hope this helps! :)

Answer:
$220 dollars
Step-by-step explanation:
a = p * w (the percentage formula)
subsitute. It rose by 30 % since last year so you're going to put 1.30 (30% -> 0.30 then add 1)
286 = 1.30 * w
solve.
w = 220
For it to double its price the price has to be +100% more, and every year you get +2.4%, so you do:
100/2.4≈ 42 years or 41.66666667.. years.
