Question 747108: I took a Pre-Algebra compass test and I did not do too good, I need to study for it and the questions were like this for example: John had $95 to buy groceries at the super market and he had to buy 6 items each costing $3.75, how much money was he left with?
So these types of questions. I cant for the life of me seem to get a study quide that teaches these types of questions Answer by josgarithmetic(39618) (Show Source):
You can put this solution on YOUR website! A question like that is below the Pre-Algebra level. You must build your basic number sense and Arithmetic knowledge before learning "Pre-Algebra". Take the course you NEED and later you can get into the course you WANT.
The sample problem presented starts with $95, and "John" does a purchase which removes $3.75, SIX times. You are asked to figure out how much money John still possesses when the purchase is finished. The very lowest-level way to do this is:
What is this last value, "itembought6"?
A more efficient way is like this:
You know John buys 6 of the item costing $3.75 each, so he spends . He will then have, instead of his original 95.00 dollars, dollars.
