Step by step explanation:
X + y=25
-y. -y
X=25-y
3x +4y= 90
3(25-y) =90
75-3y=90
-75. -75
-3y =15
/-3. /-3
Y=-5
X=25-(-5)
X= 25+5

your gross pay (pay before deductions) is $2,200.00 per month, and your take
home pay (amount of your pay check) is $1,421.00.
Question: What percent to the nearest tenth of your gross pay is deducted for

=> 799 dollars / 2 200 dollars = 0.35
=> 0.35 * 100% = 35%
Thus, 35% were deducted to his salary</span>
