Answer:
e) energy returned divided by energy invested.
Explanation:
When assessing energy resources, it is helpful to use a measure called Energy Returned On Investment (EROI), which is energy returned divided by energy invested.
Energy Returned On Investment (EROI) is a means of measuring the quality of an energy source.
Generally, EROI can be defined as the ratio of the quantity of usable energy (exergy) gotten from a specific energy resource to the quantity of energy used to produce that energy resource.
<em>Some examples of energy resources are fossil fuel, solar, hydropower, wind, nuclear, tidal, hydrogen, wave etc. </em>
Agatha's weekly allowance is 36.
<h3>What is the cost of the fidgets?</h3>
If she can afford to purchase both four fidgets and three candy bars and nine candy bars and two fidgets, it means that the cost of both options are the same.
4f + 3c = 2f + 9c
Where:
f = cost of one fidget
c = cost of one candy bar
4f + 3(2.40) = 2f + 9(2.40)
4f + 7.2 = 2f + 21.6
4f - 2f = 21.6 - 7.2
2f = 14.4
f = 14.4 / 2
f = $7.20
<h3>What is Agatha's weekly allowance?</h3>
Weekly allowance = 4f + 3c
4(7.2) + 3(2.4)
28.8 + 7.2 = $36
