alleryStart learning →A small business works out the money coming in from sales of one product. Which rule gives that amount?
AAmount sold added to the price of each
BPrice of each divided by the amount sold
CAmount sold taken from the price of each
DAmount sold multiplied by the price of each
Answer & Solution
Correct answer: D. Amount sold multiplied by the price of each
1. Money coming in from sales is worked out from how many were sold and what each one cost.
2. Selling 3 items at 5 dollars each brings in 15 dollars, which is 3 times 5.
3. So the amount is the quantity multiplied by the price, option D.
4. Adding or dividing the two would not even give an amount of money, so options A and B fail on units alone.
