Perimeter = 2 * 85 + 2 * 125 = 420
85 * 125 = 10,625 area
70 by 140 = 420 perimeter
70 * 140 = 9,800 area
Define the two friends as person A and person B.
Let x = the sales in a week.
Person A:
$125 per week plus 18% commission on sales.
Earnings in a week on x sales is
125 + 0.18x
Person B:
$85 per week plus 21% commission on sales.
Earnings in a week on x sales is
85 + 0.21x
For the two earnings to be equal,
85 + 0.21x = 125 + 0.18x
0.03x = 40
x = 40/0.03 = $1333.33
Answer: $1,333.33
1.9
9.5% = 0.095
0.095* 20 = 1.9
5+2y=-13+2y5+2y=-13+2y
Y= -40
Charles has 2/3 of bob
bob has 27
so 2/3*27 = 27 *2 = 54/3 = 18
Charles has 18
Jim has 3 times as many as Charles so he has 3 x 18 = 54
jim has 54 comic books
