Full solution

Q. Matthew has 3535 dollars more than his friend. If they have 100100 dollars all together. w much does Matthew have?
  1. Set Up Equations: Let's call the amount of money Matthew's friend has FF dollars.\newlineThen Matthew has F+35F + 35 dollars.\newlineTogether, they have F+(F+35)=100F + (F + 35) = 100 dollars.
  2. Solve for F: Now we solve for F:\newline2F+35=1002F + 35 = 100\newline2F=100352F = 100 - 35\newline2F=652F = 65
  3. Find FF: Divide both sides by 22 to find FF:F=652F = \frac{65}{2}F=32.5F = 32.5
  4. Calculate Matthew's Amount: Now we find out how much Matthew has:\newlineMatthew has F+35F + 35 dollars.\newlineMatthew has 32.5+3532.5 + 35 dollars.\newlineMatthew has 67.567.5 dollars.
