A theater offers a 20% discount to senior citizens on all tickets. The regular cost of a matinee ticket is $9.75. Which expression represents the cost of a matinee ticket after the discount is applied? A. $9.75 x 1/5 B. $9.75 x 4/5 C. $9.75 x 6/5 D. $9.75 x 9/5
Well 20% is the amount that will be taken away correct?
What grade is this?
yeahhh.
okay so the cost that will be payed is 80%, because 20% is taken away. Do you get that part?
\(\bf {\color{brown}{ 20}}\%\ of\ 9.75 \implies \cfrac{{\color{brown}{ 20}}}{100}\cdot 9.75\implies {\color{brown}{ 20}}\div 100\cdot 9.75\)
so the cost of the matinee ticket is 9.75 - (20% of 9.75)
answer is b,
or one could say, 100% - 20% = 80% as already pointed out so... what's 80% of 9.75?
4/5 is 80% so yes the answer is B.
