Keisha sold hats and shirts at a festival. She made $36 from selling hats. She also sold x shirts and made $9 for each shirt. She made a total of $99

36+9x=99

x=7

Step-by-step explanation:

36+9x=99

Subtract 99 and 36:

63

9x=63

Divide:

x=7

She sold 7 shirts

Step-by-step explanation:

The first step is to find out how much Keisha made from shirts we do this be subtracting the amounot of money she made from hats from the total

99 - 36 = 63                    now we divide 63 (amount she made from shirts) by 9 (amount each shirt sold for)

63 ÷ 9 =7

Therefore she sold 7 shirts

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
