There are 72 tokens with Riley and 63 tokens with Erik

Solution:

Riley and Erik have earned a total of 135 tokens to buy items in the school store

Total number of tokens = 135

The ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7

Number of tokens with Riley : Number of tokens with Erik = 8 : 7

Let the number of tokens with Riley be 8x

Let the number of tokens with Erik be 7x

Since, Total number of tokens = 135

number of tokens with Riley + number of tokens with Erik = 135

8x + 7x = 135

15x = 135

x = 9

Therefore,

Number of tokens with Riley = 8x = 8(9) = 72

Number of tokens with Erik = 7x = 7(9) = 63

Thus there are 72 tokens with Riley and 63 tokens with Erik
