Question

Mr.Harris has some money in his wallet. He pays the babysitter $12 an hour for 4 hours of babysitting. His wife gives him $10 and he puts the money in his wallet. By how much does the amount in his wallet change?

Answer 1

We start with -$12 an hour for 4 hours so we multiply:

-$12 * 4 = -$48

then his wife gives him $10:

-$48 + $10 = -$38

since we are looking for change and not loss or gain the answer is $38

The whole problem can be written out as (-12*4)+10

Answer 2

Well this is how much money he has in his wallet I'm assuming is 12 X 4 is 48 then 48-10 is 38, he has $38 in his wallet
