The color my room painting company charges a fixed set-up fee of $20 per job and the $0.25 per square foot to paint. let p represent the square footage of a laundry rooms walls. write an algebraic expression to find the total cost to paint the room. all is deeply appreciated.

0.25p+20

Step-by-step explanation:

Since there is a set up fee of $20 then you would have to add it to the value of what 0.25p will be. Since p represents every square foot of the walls and you would multiply p by 0.25 every square foot is $0.25 then 0.25p+20 would accurately represent the problem

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:

it’s supposed to be -4+45=41
