You need to determine what is happening in the situation maybe? If the number is increasing then it would be + or x and if they were decreasing it would be / or -
Answer:
x=5, -1
Step-by-step explanation:
set the equation equal to 0: 2x^2-8x-10=0
divide both sides by 2 to get x^2-4x-5=0
next factor your new equation to get (x+1)(x-5)
set those equal to zero
now you have x+1=0 and x-5=0
finally, solve for x by subtracting 1 and adding 5
now you have your answer x= 5 and -1
Answer:
The pay is $93.50 (if counting the 15 minutes) or $88
Step-by-step explanation:
Just calculate how many hours the person worked, and multiply that by 11. They worked 8 hours, so they get $88. If you're counting the 15 minutes the person worked too, divide 11 by 4 (there are four 15 minute segments in an hour) which is 2.75. They worked 15 minutes over an hour twice so you just add $5.50 to $88, which is $93.50.
In order to make back the money they spent ($1,137.50) plus $1500, they want to make
$2,637.50 total.
They want to make this amount by selling 350 agendas, so divide the amount they want to make by 350 to find the amount per book:
I rounded the answer to the nearest hundredth because the hundredth is the smallest amount we have in USD (the penny.)
So they need to charge at least $7.54 to make back their money plus $1500.
Hope I helped, and let me know if you have any questions :)
