Question

Determine which word problem represents the given algebraic expression.
925(1+r4)exponent 4t

Yvette got a new job that pays $4 per time, t . If her first paycheck is $925, find the total earnings at a tax rate, r .

Monica started a bank account with the principle amount of $925 . Find the balance of Monica's account with rate, r , for t years, that will be compounded 4 times a year.

Answer 3

@iPwnBunnies

Answer 4

it looks like the compound interest formula to me

that's providing its r/4

Answer 5

so then what would be the answer @campbell_st

Answer 6

well to me the compound interest formula with 4 compounding periods is

\[A= P(a + r \div 4)^{4t}\]

where P is the initial investment r is the interest rate as a decimal...

dividing r by 4 adjusts the interest rate to accommodate 4 compounding periods.

and t is the time in year.. so since there are 4 compounding periods it becomes 4t

Answer 7

so would the answer be c @campbell_st

Answer 8

I think its the Monica statement

Answer 9

are you sure @campbell_st

Answer 10

I'm really not sure...as I asked if the equation has r/4 rather than r4, to which you didn't reply...

So I'd say mine is an educated guess

Answer 11

ok i got it thank you
