Juanita and Keenan own a camping supply store and just put in an order for flashlights and sleeping bags. The number of flashlig

julsineya [31]

Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.

Step-by-step explanation:

Given,

Cost of each flashlight = $12

Cost of each sleeping bag = $45

Total cost = $1785

Let,

x represent the number of flashlights ordered

y represent the number of sleeping bags ordered

According to given statement;

12x+45y=1785 Eqn 1

x = 5y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$12(5y)+45y=1785\\60y+45y=1785\\105y=1785\\$

Dividing both sides by 105

$\frac{105y}{105}=\frac{1785}{105}\\y=17$

Putting y=17 in Eqn 1

$x=5(17)\\x=85$

Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.
