Your mom opens an account to save money for a family vacation. the account earns an annual interest rate of 4%. she earns $37 in simple interest after 6 months. how much money did she put in the account when she opened it?

$1,850 is the correct answer. When you divide the interest ($37) by the time in years (0.5) and the interest rate (0.04), you get the correct amount of principal.

That's straight from the source. I feel so bad that your question didn't get answered. It's legit been two years

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
