Answer :
2:3 ratio
His dad pays 52.5, divide 3 to that:
52.5 / 3 = 17.5
Multiply this to 2:
17.5 * 2 = 35
This is what Adam pays, now add this to what his Dad pays to find the total:
35 + 52.5 = 87.5
So the total cost of the meal is $87.50
His dad pays 52.5, divide 3 to that:
52.5 / 3 = 17.5
Multiply this to 2:
17.5 * 2 = 35
This is what Adam pays, now add this to what his Dad pays to find the total:
35 + 52.5 = 87.5
So the total cost of the meal is $87.50
the total cost is divided in the ration 2:3
we can take it as Adam pays 2 parts and Adams dad pays 3 parts
the amount that Adams dad pays is 52.50
Adams dad pays 3 parts thats equivalent to - 52.50
then one part is - 52.50 / 3 = 17.50
the total cost is divided in the 2:3 ratio therefore total cost is equivalent to 2+3 = 5 parts
one part is equivalent to 17.50
therefore 5 parts are equivalent to - 17.50 x 5 = 87.50
the total cost of the meal is 87.50
