Sophieee:

Am I allowed to say the steps to find the answer?

martai:

yes

Sophieee:

Kk so first change the percent to a regular number by moving the decimal place 2 times so 7.1% becomes 0.071 then do 0.071 × 2500 then since it's over 5 years do The answer to 0.071 x 2500 times 5 and you get your answer

martai:

oki got it now

martai:
