Answer:
3 pens.
Step-by-step explanation:
x+y=7 where x is # of pens and y =# of pencils
3x + 2y= $18
from first equation, x=-y+7 so substitute that into other equation
3(-y+7)+2y=18
-3y+21+2y=18
-y=18-21
-y=-3
y=3
now replace y =3 into first equation
x+3=7
x=4
To solve this problem, you want to find how much Kristen gets paid per hour, by each person.
Mrs. Carson: $48=6x => x=$8 per hour
Mrs. Vasquez: $67.50=9x => x=$7.50 per hour.
Since Mrs. Carson gives Kristen a larger hourly rate, she gets a better salary than from Mrs. Vasquez. Hope this helped!
