Answer:
1) $3
2) $1.2
Explanation:
1) First, we have to calculate the appropriate compensation for Kate, which is given by the increase in price of the drink for the number of drinks consumed by Kate:
ACK=0.30*10= $3
ACK=3
2) Now, the proper compensation for elisa (we calculate it the same way we do for Kate) is given by:
ACE=0.30*4= $1.2
ACE=1.2
