The ticket price for an ice hockey match used to cost ?19.60. The price has now increased by 12.5%. How much will 2 tickets cost

JulijaS [17]

ANSWER: $44.10

EXPLANATION: The actual cost for an ice hockey match is $19.60. Now, if the price of the ticket increases by 12.5%, the cost of each ticket will increase by $2.45.

$19.6 x 12.5% = $2.45

So, the final price of a single ticket will be $22.05

$19.6 + $2.45 = $22.05

Hence, the cost of two tickets after the increase will be $44.10

$22.05 x 2 = $44.10

Hence, Given relation is not a function.
