The new balance on Jane Hilman's account is the answer when we add up all the previous balance, the credit, and the negative of the amount she withdrew. This gives us,
new balance = $1009.88 + $6.19 - $130
The numerical answer to the equation above is $886.07.
hi
u0 = 64 with u(n+1) = un *0.75
u3 = 64 *0.75^3 = 27
sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175
manual proof : 64 + 48+36+27 = 175
