70, 7*10 since it is 1/10 of that number
The answer is $10
if you add up the total price for each of the items it totals to $40, she has $50 so $50-$40=$10
If the total amount of points in a test is 140, and we want to find 10% of those points, we can do the following to figure out how much points the question is worth...
140 points x 10% = 140 x 0.1 = 14 points for the short-answer quesion.
No because the hundred place doesn't move.
