Final answer:
Parth spends $20.90.
Step-by-step explanation:
To find how much Parth spends, we need to add up the amounts spent by Hunaid, Younis, and Parth. We are given that Hunaid spends $3.35.
Younis spends 4 times as much as Hunaid, so we multiply $3.35 by 4: $3.35 * 4 = $13.40.
Parth spends $7.50 more than Younis, so we add $13.40 and $7.50: $13.40 + $7.50 = $20.90.
Therefore, Parth spends $20.90.
