Sonya has X amount of money. Bob has three times as much as Sonya has, less $14.62. Write an expression , using X, that tells how much does Bob has. I need to know if the expression will be x= 3x-14.62 and the answer will be $7.31. Thank you for helping me.
"Sonya has X amount of money. Bob has three times as much as Sonya has, less $14.62. Write an expression , using X, that tells how much does Bob has."
You're only trying to find an expression to describe Bob's money. You're on the right track with "3x - 14.62" -- and in fact that is the correct answer.
If you say that "x = 3x - 14.62" you imply that Sonya's money (x) = Bob's money (3x - 14.62).
thank you for your help
3x-14.62
To find the expression that tells how much money Bob has, we can break down the given information step by step.
First, we know that Sonya has X amount of money.
Then, we are told that Bob has three times as much as Sonya, less $14.62.
To express this mathematically, we need to multiply Sonya's amount by 3, and subtract $14.62:
Bob's amount = 3 * Sonya's amount - $14.62
Since Sonya's amount is X, we can substitute it into the expression:
Bob's amount = 3X - $14.62
Therefore, the correct expression to represent how much money Bob has is 3X - $14.62.
To verify if the answer will be $7.31 when X = 1, we can substitute X = 1 into the expression:
Bob's amount = 3 * 1 - $14.62 = 3 - $14.62 = -$11.62
As you can see, when X = 1, the answer is not $7.31. Therefore, the given expression is incorrect.
