Answer:

C. 10.15

Step-by-step explanation:

If you left 8.25 and changed the minus sign to a addition sign and the -1.9 to just 1.9 and then add 8.25 + 1.9 together you will then get 10.15 a way to remember this is “leave, change, change,” you leave the first number and change the subtraction and negative number sign. :)

The answer is C. 10.15 because two minus signs become a positive a.k.a when you subtract a positive with a negative it becomes 8.25 + 1.9
