there are 10 dimes. that is 1/4 of the all the coins. So we can do 1380/4=345. Since 1380 is including the 10 dimes, 345*10=3450. Then we add the decimal point at 34.50 as this is USD and 100 cents in a dollar
I think the answer would be D. There is 30 students from each grade so we have 30/120 already then add 12 from 9th grade math and add 10 more from 10th grade math, then add 7 from 12th grade math. 30 + 12 + 10 + 7 = 59 59/120 students.
Hi there The formula is A=p (1+r)^t A future value 14400 P present value 1200 R interest rate 0.04 T time? We need to solve for t T=log (A/p)÷log (1+r) So T=log(14,400÷1,200)÷log(1+0.04) T=63.4 years
