3 weeks = 21 days
Let Jerrad's vacation be X then Max's be 2X and Wesley's 4X
X+2X+4X=21
7X=21 devide by 7
X=3 so Jerrad had 3 days vacation
2*3= 6 Max had 6 days
4*3=12 Wesley had 12 days vacation
The jeans were $10.00 before 15% tax.
So x+0.15x=11.50
1.15x=11.50
x=10
4 fifths of 30 is 24 because if you divide 30 by 5 it is 6 and is you multiply 6 by 4 you get 24
