Pat had $3.he gets some money from his parents .he now has twice as much money as dani .write an expression to represent how much money dani has.tell what the variable represents .
2d=p
d=dani
p=pat
let the amount Pat gets from his parents be x
So now he has x + 3
This is twice what Dani has
x+3 = 2(Dani)
Dani = (x+3)/2
To write an expression representing how much money Dani has, we'll start by assigning a variable. Let's say we assign the variable "D" to represent Dani's money.
Given that Pat has $3 and now has twice as much money as Dani, we can write the expression as follows:
2D
In this expression, the variable "D" represents the amount of money Dani has. By multiplying "D" by 2, we are expressing that Pat has twice as much money as Dani.
