Question

Francis owns a camping supply store and just put in an order for flashlights and sleeping

bags. The number of flashlights ordered was five times the number of sleeping bags ordered.
The flashlights cost $12 each and the sleeping bags cost $45 each. If the total cost for the
flashlights and sleeping bags was $1785, how many sleeping bags did Francis order?

Answer 1

The number of sleeping bags bought is 17.

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.
