This is the simplified way
Saturn is about 10 times as far as earth from the sun
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

Dividing both sides by 105

Putting y=17 in Eqn 1

Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.
