Atoddler was given 12 boxes of crayons, each of which contained 12 crayons. within a week, he eventually lost half of the crayons and broke a quarter of the remaining crayons. how many intact crayons did the toddler have at the end of the week?

12 x 12 = 144 crayons in total 
144 / 2 = 72 crayons lost 
72 / 4 = 18 crayons broken 

144 - 72 - 18 = 144 - 90 = 54 intact crayons left

I believe the answer is 54. If you need me to write out how I solved it I can.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
