Question

Find how much was invested
at each rate if $20,000 more was invested at 7%
than at 5%

what would be its equation​

Answer 1

Answer:

t = Time

Step-by-step explanation:

A = X(1+.05)^t using X as the initial investment, compounded yearly

For $20000 more invested at 7%,

A' = (X+20000)(1+.07)^t
