Answer:
The number of sleeping bags bought is 17.
Step-by-step explanation:
If we let "x" be the number of the sleeping bags that were bought, we can make the following equation....
(5x)(12) + (x)(45) = 1785
By solving the equation we get....
(5x)(12) + (x)(45) = 1785
60x + 45x = 1785
105x = 1785
x = 1785 / 105
x = 17
There for the number of sleeping bags bough is 17.
