So you would set this problem up as 10 x 9 x 8 x 7, since none of the digits can be repeated. There are 5,040 4 digit passcodes possible.
step by step explaination:
ending balance=$30000
30000*5.5
165000÷6=27,500
compound interest =27,500
16*2=32
32-.25(1.5 teaspoons) =31.75
31.75 ounces of pepper
Your answer to your question is 51
From this equation C°=[F°-32]÷1.8
F°=158×1.8 +32=316.4°
