Denver nickel is valued at $9, and Philadelphia is valued at $6.

#### Explanation:

Given: The $D$ nickel has a higher value than the $P$ nickel because the fraction size is larger than $1$. We have two unknown values.

We can write: $D = \frac{3}{2} P$

We also know that D + P = $15 Then we can substitute the $P$value for $D$from the first equation into the second: 3/2 P + P =$15

5/2 P = $15 5P =$30

P = $6 $D = \frac{3}{2} P$2D = 3($6)

2D = $18 D =$9

Check: D + P = $15 $9 +$6 =$15#
