The sum of two numbers is 640. if you divide the bigger number by the smaller, you’ll get quotient 7 and remainder 64. find the numbers.

let 'x' and 'y' represent the two numbers and x>y

The sum of two numbers is 640:

x + y = 640

If you divide the bigger number by the smaller, you’ll get quotient 7 and remainder 64:

x = 7y + 64

by solving the system of equations:

x + y = 640

x = 7y + 64

we find:

x = 568

y = 72

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
