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.
Answer:
1080 calories
Step-by-step explanation:
all you do is add 120 everytime she goes on run
let the number of adult tickets be x and the number of children tickets be y
3x + y = 164...equ(1)
2x + 3y = 174....equ(2)
multiplying equation 1 by 3
9x + 3y = 492
subtracting equation 2 from 1
7x = 318
x = 45.43 dollars
substituting the value of x into the equation
3(45.428) + y = 164
y = 164 - 3(45.428)
∴y = 27.71 dollars
