Step-by-step explanation:
the original is 40 and discount is 28% so $40-28%
<em><u>142.34 divide by 24 will give you the answer of 593.083 ----> </u></em>
<em><u>24 x 5 will equal 120 which is close to 142 then subtract 120 by 142 which will give you 22 then bring down the 3 and you will have 223 which 24 x 9 will give you 216 then subtract 223 -216 which gives you 74 then 24 x 3 = 72 then you add a decimal then a zero which is 20 then add another zero which is 200 then multiply 24 by 8 which is 192 and then subtract 200 by 192 and get 72 and then your answer will keep on going</u></em>.
