Answer:
3/7
Step-by-step explanation:
There are 7 possible outcomes on this spinner. There are 3 odd numbers, so your odds of landing on odds is 3/7.
Let x be the amount earned by Tony. With this representation, Jennifer earned 2x - 40 and Chris earned x + 60. The amounts they earned should sum up to 900. The equation is,
x + (2x - 40) + (x + 60) = 900
The value of x is 220. Therefore, Tony earned $220. Jennifer and Chris earned $400 and $280, respectively.
