The check$-$cashing store also makes one$-$month add$-$on interest loans at $7\mathrm{.}8$ percent discount interest per week. Thus if you borrow $$200$ for one month $($four weeks$),$ the interest will be $($$$2001\mathrm{.}0784)=$$$70\mathrm{.}09$$$2001\mathrm{.}0784=$$$70\mathrm{.}09.$ Because this is discount interest, your net loan proceeds today will be $$129\mathrm{.}91.$ You must then repay the store $$200$ at the end of the month. To help you out, though, the store lets you pay off this $$200$ in installments of $$50$ per week. What is the APR of this loan? What is the EAR?

Note:Do not round intermediate calculations and enter your answers as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
