2X^2+22x+318=1270
2x^2+22x-952=0
x^2+11x-476=0
(x+28)(x-17)=0
x=17
Okay what problem is it that you need help with??
First, convert the 17% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 17%) by 100%.So, the conversational term "17%" becomes 17% / 100% = 0.17 in terms of a real mathematical number.
Second, you need to find out what 17% of your $24.50 meal cost is.This is always done by multiplying 0.17 by $24.50
0.17 x $24.50=$4.16.
So, the amount of tip you are going to leave is $4.16.
This makes the total cost of your meal (to write on your charge slip or other payment)
$24.50 + $4.16 = $28.67.
A= 20 cause 5-2=3 and if the top is 23 it has to be 20
2+2 is 4 minus one that's 3 quick maths but 2+1 is equal to 3
