If you want to check my answers
use substitution method by using the x into for each equation.
If X is the number of hats . . . reading backwards . . .
Thursday = Wednesday + Tuesday
17 = 1/2 X + 5
Solving:
17 - 5 = 1/2 X
12 = 1/2 X
24 = X
So she had 24 on Monday.
I think its the second one
Monthly salary of Kedar = $2000
Percentage commission on the amount of his sales = 3.75%
Amount of money for which clothing sold by Kedar = $4500
Amount of interest earned by Kedar this month = (3.75/100) * 4500
= 3.75 * 45
= 168.75 dollars
So
The total amount earned by Kedar this month = (2200 + 168.75) dollars
= 2368.75 dollars
So Kedar earned a total amount of $2368.75 this month.I hope the procedure is absolutely clear to you.
