Answer
(a) Tomas sells
small boxes and 8 more large boxes than the small boxes. The number of large boxes he sells would therefore be equal to the number of the small boxes plus 8. At this point, we can express the number of large boxes he sells as:
We have the variable
representing small boxes already. The number of large boxes is realized by adding 8 to the number of small boxes; hence we have
. (b) If Tomas sells each small box with 6 eggs and each large box with 10 eggs, we can measure the total number of eggs by adding the product of the number of small boxes and 6 to the product of the number of large boxes and 10.The number of eggs in the small boxes:
Recall that the number of large boxes he has is given by the expression
.The number of eggs in the large boxes:
Therefore, the total number of eggs Tomas sells in small and large boxes is given by the sum of the two previous expression:
To simplify, we add like terms: i.e.,
to get :
The answer is that the number of large boxes sold is equal to
and the total number of eggs sold is
.
