Ihave tried a couple of equation but none of them worked. .

Let's start with the information we know. 

Aiden gets $85 a month
Over 7 months, he has saved (85*7 = 595) $595
He will need to have $1955 for the laptop

1955 -

Now figure out how many months he will have to spend to get 1955 - the 595 he already has (1360 is what that comes out to.) 1360 (The total he will need) / 85 (The number you get a month)

That equals 16.
It will take Aiden at his current rate of income, 16 months to save for his new computer. 

--Something to remember--

If the number you come out with is a decimal, I.E. 16.2, you will need to round up to the nearest whole number unless the equation specify's. In this case, instead of 16.2 it would be 17 months

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

59/96 is the ratio hope this not 100% sure though : /
