In this item, we let the number of tickets sold to the adults as x. With this, we can let the number of tickets sold to students with y.
In this item, we are given that the sum of the number of students and adults is equal to 600. Further, we are also given that the difference is 150. The system of linear equation that would allow us to solve this item is,
x + y = 600
x - y = 150
Adding up the two equations will give us,
2x = 750
Dividing by 2,
x = 375
Substituting this value to the first equation,
375 + y = 600
y = 225
Therefore, there are 375 and 225 number of tickets sold to adults and students, respectively.
Answer:
c. sunk cost.
Explanation:
Because in short run, fixed cost doesn't changes with output, that is whether we produce or not, we have to pay for it, so it is considered as Sunk cost. Also like Sunk cost, we don't make decisions with fixed costs.
Answer:
C. less than 1
Explanation:
Supply is elastic if producers can increase output without a rise in cost or a time delay which means Price elasticity of supply is more than 1.
Supply is inelastic if producers find it hard to change production in a given time period which means Price elasticity of supply is less than 1.
When Price elasticity of supply equals 0 then supply is perfectly inelastic.
The company's return on investment ROI would be 12.5%
What does a favourable return on investment mean?
The profit from an investment is divided by the investment's cost to determine the return on investment (ROI). When represented as a percentage, an investment with a profit of $100 and a cost of $100 would have a ROI of 1, or 100%. Generally speaking, a yearly ROI of around 7% or higher is regarded as a decent ROI for an investment in stocks. This also refers to the S&P 500's average annual return when inflation is taken into account of the company to increase the profit margin.
