Denise earns $30 an hour. She works 40 hours per week. Denise would like to purchase a computer that costs $2000. Create and solve an inequality in order to determine the least amount of hours she must work in order to be able to purchase the computer?

Step-by-step explanation:

Given

she works $30 for 1 hour

in 40 hours she will earn 40*30= $1200

this means that a week she earns $1200

let the number of  weeks she needs to work be x

40x*(30)<=2000

1200x<=2000

x<=2000/1200

x<=1.66

the number of hours in a week is 40

40*1.66=66.66

67hours

hence she must work for at least 67hours

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
