Answer:
After the increment in price the cost of attending the event [tex]=\$ 119[/tex]
Step-by-step explanation:
Before the purchase deadline the cost [tex]=\$ 85[/tex]
Now after the deadline the cost have increases [tex]40 \%[/tex]
So this increment is incurred with the initial cost of attending the event.
We have to to find what is exactly [tex]40\%[/tex] of [tex]\$85[/tex]
So [tex]40\% =\frac{40}{100}=0.40[/tex]
Then we will multiply this with the initial cost.
Increment, [tex]=0.40\times \$85 =\$34[/tex]
Now the cost after the increment [tex]=(\$85+\$34)=\$119[/tex]
Final cost of attending the particular event [tex]=\$119[/tex].
