Please help, what operation should I use to solve this problem? Jessica bought 10.50 pounds of potatoes. The potatoes are sold in sacks of 20 if the potatoes cost $1.99 per pound. How much money did Jessica spend?
10.5 x 1.99 =
Simple multiplication
Which gives you 20.895 and you round up to 21.00, but if you want to get 20 don't round of course.
Lauren -- The question asks how much money did she spend. Your answer is not correct.
20.895 = $20.90
To find out how much money Jessica spent on potatoes, we can multiply the weight of the potatoes by the cost per pound. In this case, Jessica bought 10.50 pounds of potatoes and they cost $1.99 per pound.
So, to find the total cost, we can use the multiplication operation:
Total cost = Weight of potatoes * Cost per pound
Total cost = 10.50 pounds * $1.99/pound
To solve this problem, multiply the weight of potatoes (10.50) by the cost per pound ($1.99). Let's do the calculation:
Total cost = 10.50 * 1.99
Multiply the whole number (10) by the whole number (1) to get 10. Then, multiply the decimal (0.50) by the whole number (1) and by the decimal (0.99) to get 0.495. Finally, add together 10 and 0.495 to get 10.495.
Total cost = $10.495
Therefore, Jessica spent $10.495 on the potatoes.
