This answer is incorrect.
To complete this problem, you must first divide the number of tapes by 10 to find out how many boxes you will need for each type of tape.
178 divided by 10 = 17.8 boxes
121 divided by 10 = 12.1 boxes
Therefore you will need 17.8 boxes for the first kind of videotape and 12.1 boxes for the second kind of videotape. You, of course, cannot actually get .8 or .1 boxes so you will have to round up in both cases. In reality you will need 18 boxes for the first kind of tape and 13 boxes for the second kind of tape.
Therefore, the total number of boxes you will need is 18 + 13 which is 31.
Now let's try another problem.
Sam had to pack circuit boards 12 to a box. If he had 223 circuit boards of one type and 325 of another type, how many boxes would he need in order to pack them all and not mix the types of circuit boards?
