Answer: B.
Step-by-step explanation: This is because you can't possibly have an exponent, there are no two of the same value being multiplied together.
Answer:
After a year you would have $1,825
Step-by-step explanation:
Amount for one cat a day in cents
10x25=250
Amount for one cat for a year in cents
250x365=91,250
Amount for both cats for a year in cents
91,250x2=182,500
Amount for both cats for a year dollars
182,500/100=1,825
For this case, the first thing we must do is define variables.
We have then:
x: number of pens
y: number of pencils
We now write the system of inequations:

The solution to the system of inequations is given by the shaded region.
