The formula A=P(1+rt) calculates the ending balance, A, of a principal amount, P, of earning simple interest at a rate of r after t years. Nishi has an ending balance of $134.00 for a principal amount that she invested at 5% simple interest for 2 years. Which was the principal amount in Nishi's account?

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to

Y=-3x is the correct answer
