Answer: $9.48 or $9.47
Step-by-step explanation:
Total is $11.50 so far, discount is 20%. Add tax later to make it a little more simple.
20% can be written as 20/100 then simplified down to 1/5 So, another way to get the discount is to just divided $11.50 by 5, which is, $2.30, subtract it from $11.50 you get $9.20 as the new total. Time for the tax,
3% or 3/100 can be written as 0.03. Using this we can find the new cost by multiplying $9.20, which is, approximately 0.28, Add it, you get $9.48 or $9.47 depending on whether or not it wants you to round.
