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.
