I am setting the week hourly rate to x, and the weekend to y. Here is how the equation is set up:
13x + 14y = $250.90
15x + 8y = $204.70
This is a system of equations, and we can solve it by multiplying the top equation by 4, and the bottom equation by -7. Now it equals:
52x + 56y = $1003.60
-105x - 56y = -$1432.90
Now we add these two equations together to get:
-53x = -$429.30 --> 53x = $429.30 --> (divide both sides by 53) x = 8.10. This is how much she makes per hour on a week day.
Now we can plug in our answer for x to find y. I am going to use the first equation, but you could use either.
$105.30 + 14y = $250.90. Subtract $105.30 from both sides --> 14y = $145.60 divide by 14 --> y = $10.40
Now we know that she makes $8.10 per hour on the week days, and $10.40 per hour on the weekends. Subtracting 8.1 from 10.4, we figure out that she makes $2.30 more per hour on the weekends than week days.
Yes the answer is ymb=y your welcome
Numbers 5 and over round up to the nearest 10. Numbers like 164 would found to the nearest 10 of 160 because the last number (unit) is below 5, so it rounds down. I hope this helps but you can find tutorials on google good luck!
Answer:
x = 33, y = 17
Step-by-step explanation:
1) the sum of all the angles in any triangle is 180 degrees
2) when 2 lines intersect, the angles opposite each other are equal
3) the sum of any angles that break up one side of a straight line is 180
