Answer:
54 is the answer
Step-by-step explanation:
18 times 3
Complementary means sum = 90, so 90-57 to get the other angle at 23 degrees
Supplementary means sum = 180, so 180-52 to get the other angle at 128 degrees
100-64=36 percent wrong
if 36% is 18 questions
then, 36/18=2
every question is 2% grade
100/2=50 questions in total
Turn 30% into a decimal 0.30 then times it by 129 =£38.70
£129.00-£38.70=£90.30 that be the discount.
6.25=0.0625 as decimal then times it 129.00=£8.06 which is the tax.
£90.30+£8.60
New price £98.90
