You purchased an annuity in which you deposit $$100$ a week at a fixed rate of $4\%$ interest. What formula would you use to calculate its value at the end of $10$ years?

a$.=$PMT$(\mathrm{.}04/12,12*120,100)$

b$.=$FV$(\mathrm{.}04/12,520,100)$

c$.=$FV$(\mathrm{.}04/12,10*52,-100)$

d$.=$PMT$(\mathrm{.}04/12,12*120,,-100)$
