The ratio of ed’s toy cars to pete’s toy cars was initially 5: 2. after ed gave 30 toy cars to pete, they each owned an equal number of toy cars. how many toy cars did they have altogether?

Lets go up from the decreased ratio of 5:2 by multiplying by 20

20×5=100
2×20=40

so now the ratio is 100:40

100-30=70
and 40+30=70

so they both have 70.

so Ed probably had 100, and Pete had 40. Ed felt sorry for his friend and wanted him to have the same amount of toy cars that he did so that his friend would not be jealous. so for Christmas Ed gave 30 of his cars to his friend Pete and then they both had 70 toy cars each. The End.
