a dinner for 4 people would cost $62.50. If James wants to leave a 20% tip onto the cost of the meal, how much would each person pay?

Answer 1

Assuming they will all pay equaliy, including the tip,
100=orignal
100+20=120

120% of 62.50
ssimlify it
120/4=30
30% of 62.50=0.3*62.5=18.75

each person pays $18.75
