<span>Divide $380 by 20 and then multiply the result by 7. Its really not hard I promise I basically just gave you the answer</span>
Answer:
the least common multiple is 18
Step-by-step explanation:
In economics, the downward sloping demand curve is used to illustrate the law of diminishing marginal utility. This means that if more of the product is consumed, the marginal benefit to the consumer falls. This is also the instance in which the consumers are willing to pay less than the original amount for the same product.
So we have the equation:

Then we need to multiply by 4 on both sides to get rid of the denominator on the left:

Then we subtract 9 on both sides to solve for z:

Therefore the answer is z = -0.6.
