Final answer:
When analyzing the effect of a price increase on total revenue, the price elasticity of demand needs to be considered. If demand is elastic, a price increase will lead to a decrease in total revenue per week. If demand is inelastic, a price increase will lead to an increase in total revenue per week.
Step-by-step explanation:
When analyzing the effect of a price increase on total revenue, we need to consider the price elasticity of demand. If demand is elastic (elasticity greater than 1), a $10 increase in price will lead to a decrease in total revenue per week. This is because the increase in price will result in a proportionately larger decrease in the quantity of scooters sold. On the other hand, if demand is inelastic (elasticity less than 1), a $10 increase in price will lead to an increase in total revenue per week. This is because the increase in price will result in a proportionately smaller decrease in the quantity of scooters sold.
