Question

Alaina has $72 and earns $6 each day. Joel has $48 and earns $8 each day. In how many days will Joel have as much money as Alaina?

Answer 1

8x + 48 = 6x + 72

Answer 2

So anyway set them equal to each other because the problem says they both have an equal amount of me on X number of days. Therefore you have to solve for X in this problem

Answer 3

I see so when it says "How many days will Joel have as much money as Alaina that means how many days will they have equivalent (=) money right?

Answer 4

What I would do is subtract 6x from both sides and subtract 48 from both sides you get 2x = 24 divide by two and x = 12

Answer 5

x=12, right?

Answer 6

Yes exactly

Answer 7

Therefore in 12 days they will both have the same amount of money. you did it (;

Answer 8

In my head

Answer 9

So if i graphed it, what would be the point where they have same amount of money

(12, ?)

Answer 10

It would be helpful if you asked your second question :P

Answer 11

according to my calculations if your asking how much money they would both have it would be (12, 144)

Answer 12

Alaina has $72 and earns $6 each day, Joel has $48 and earns $8 each day. In How many days will joel have as much money as Alaina?

A=72($)+6($/day)*D(day)
J=48($)+8($/day)*D(day)

A=J (Alaina and Joel must have the same ammount of money)

(72+6D)($) = (48+8D)*($) (note that system units is $-money and simplifies at the end)


24=2D
D=12

Answer 13

We established that..:P
