Denise earns $30 an hour. She wants to purchase a computer that costs $2000. Create and solve an inequality to determine the least amount of hours she must work in order to be able to purchase the computer.
Answer:

Denise has to work at least 67 hours in order to buy a computer that costs $2000.
Step-by-step explanation:
Given:
Hourly earning of Denise is $30.
Let the number of hours Denise works be 'h'.
Now, total earning of Denise can be calculated using the unitary method and is given as:

Now, total money earned by Denise must be at least $2000 in order to purchase a computer. Therefore, the inequality is given as:

Therefore, Denise has to work at least 67 hours in order to buy a computer that costs $2000.

56,000.0
Step-by-step explanation:
The number 6 is in the nearest thousand. To round, you look at the number in front of the number you are trying to round and decide if that number is higher or lower than five. If the number is higher than 5, round up to the next highest number. If the number is lower than 5, the number stays the same.
To find the number or rows, divide the total number of students by the number in each row.
63 / 7 = 9 rows.
