Two plus ten times eight
(2+10)*8 = 96
Answer:
2.5 or 2 1/2
Step-by-step explanation:
divide 15 by 3 and you'll get 5. multiply 1/2 by 5 and you get 2.5
Answer:
f*2.5 + 40 = 100
Step-by-step explanation:
f*2.5 + 40 = 100
f = (100 - 40) / 2.5
f = 24
Bearing in mind the compounding is weekly on an APR, so the compounding cycle is 52, since there are 52 weeks in a year
however, the maturity term in years, is just 50/52, since is 50weeks from 52 in a year, so is 50/52 years, which is just a fraction of a year

solve for P
"Ten times a number plus 9" Is the correct way to write this equation.
