Marie has 231 toothpicks in one box and 175 toothpicks in another box. She uses 319 toothpicks to make a bridge. How many toothpicks does she have left

87 toothpicks

Step-by-step explanation:

If Marie has 231 toothpicks in one box and 175 in the other, you can add them together which would get:

      231

+     175

     406

If Marie uses up 319 toothpicks, then you would have to subtract the 319 toothpicks from the 406 toothpicks in order to see how much is left:

    406

-    319

      87

which would leave you with 87 toothpicks left!

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
