Question

One ticket to a show costs $20 at full price. Susan buys 4 tickets using a coupon that gives her 25% discount.

Answer 1

Answer: $\ 60$

Step-by-step explanation:

Given

One ticket costs $20

Susan buys 4 tickets with 25% discount

Cost of 4 tickets is $4\times 20=\ 80$

On applying discount, it costs

$\Rightarrow 80-80\times 0.25\\\Rightarrow 80(1-0.25)\\\Rightarrow 80\times 0.75=\ 60$

So, total cost of tickets is $\ 60$.
