First we multiply 7 and 0.15 to see how many he lost. We get 1.50 so now we know he lost 1.50 of his collection. we add 5.55 and 1.50 and get 7.05 we divide 7.05 by 0.15 47.

Tony had 47 stamps

Helga [31]

<u>Answer:</u>

  • Colin will have $2365 after 3 years.

<u>Step-by-step explanation:</u>

<u>Using PRT/100, we can find the interest and then sum it up with the principle amount.</u>

  • => 2200 x 2.5 x 3/100 = Interest
  • => 22 x 2.5 x 3 = Interest
  • => 55 x 3 = Interest
  • => 165 = Interest
  • => 2200 + 165 = Total amount
  • => $2365

Hence, <u>Colin will have $2365 after 3 years.</u>

Hoped this helped.
