Julie loves candles and bought many for different prices at a market. She bought 7 at 3 dollars each, 5 at 6 dollars each, 9 and 9 dollars each and 3 at 12 dollars each. In her purse, Julie originally had four 50 dollar notes.
Write an equation to show how much money Julie had remaining after her purchases
four 50 dollar notes = $200
money left = 200 - 7*3 - 5*6 - 9*9 - 3*12
= ....
Let's calculate the total amount spent by Julie on candles first.
Number of candles bought at $3 each = 7
Cost of each candle = $3
Total spent on candles at $3 each = 7*3 = $21
Number of candles bought at $6 each = 5
Cost of each candle = $6
Total spent on candles at $6 each = 5*6 = $30
Number of candles bought at $9 each = 9
Cost of each candle = $9
Total spent on candles at $9 each = 9*9 = $81
Number of candles bought at $12 each = 3
Cost of each candle = $12
Total spent on candles at $12 each = 3*12 = $36
Now, let's calculate the total amount spent by Julie:
Total amount spent = $21 + $30 + $81 + $36 = $168
Since Julie originally had four $50 notes, the total amount of money she had initially was:
Total initial amount = 4 * $50 = $200
To find out how much money Julie had remaining after her purchases, we can subtract the total amount spent from her initial amount:
Remaining amount = Total initial amount - Total amount spent
So, the equation to show how much money Julie had remaining after her purchases is:
Remaining amount = $200 - $168 = $32
To find out how much money Julie had remaining after her purchases, we need to calculate the total cost of the candles and subtract it from the original amount of money Julie had.
First, let's calculate the total cost of the candles. Julie bought 7 candles at 3 dollars each, so this would cost her 7 * 3 = 21 dollars. She bought 5 candles at 6 dollars each, so this would cost her 5 * 6 = 30 dollars. She also bought 9 candles at 9 dollars each, so this would cost her 9 * 9 = 81 dollars. Finally, she bought 3 candles at 12 dollars each, so this would cost her 3 * 12 = 36 dollars.
To find the total cost, we add up the costs of the candles: 21 + 30 + 81 + 36 = 168 dollars.
Now, to find out how much money Julie had remaining, we subtract the total cost from the original amount of money Julie had. She originally had four 50 dollar notes, so she had 4 * 50 = 200 dollars.
Let's represent the amount of money Julie had remaining with the variable "R".
The equation can be written as:
R = 200 - 168
Simplifying the equation:
R = 32
So, Julie had 32 dollars remaining after her purchases.
Hope this helps!
