Adam pays for 2/5 of the meal so his father pays for 3/5
3/5 = 52.50
1/5 = 52.50 / 3 = 17.50
so cost of the meal = 5 * 17.50 = $87.50

Answer:
$42.14
Step-by-step explanation:
You add 14% to 42.00
Knowing that pluto is travelling at 10,604 and the Earth travels 6.28 times faster;
6.28x=10,604 mph (where x is the speed of the earth)
x=10,604/6.28
x=1688.53 mph for the Earth
Double check by multiplying the answer found by 6.28 to see if it gives pluto's speed.
1688.53×6.28=10, 604 mph
Therefore, our solution is correct.
Hope I helped :)
