Answer:
the bigger number is 42
the smaller number is 10
Step-by-step explanation:
use algebra to denote:
let x be the bigger number
let y be the smaller number
x+2y=62...(1)
3x-y=116...(2)
x=62-2y...(1a)
substitute
3(62-2y)-y=116
186-6y-y=116
-7y=116-186
-7y=-70
y=-70/-7
y=10
therefore x is:
x=62-2(10)
x=62-20
x=42

Answer:
$2.20
Step-by-step explanation:
Original price (before discount and before tax): $5
Discount is 60%.
Amount of discount is: 60% of $5 = 0.6 × $5 = $3
Price after 60% discount: $5 - $3 = $2
Tax is 10%.
Amount of tax is: 10% of $2 = 0.1 × $2 = $0.20
Final price = price after discount + tax = $2.00 + $0.20 = $2.20
