Seven US Dollars $($7)$ .

Since

$"1 penny = $0.01"$

$"1 nickel = $0.05"$

$"1 dime = $0.10"$

$"1 quarter = $0.25"$

you have

$"15 pennies" = ($0.01xx15)= $0.15$

$"7 nickels" = ($0.05xx7)= $0.35$

$"15 dimes" = ($0.10xx15)= $1.50$

$"20 quarters" = ($0.25xx20)= $5$

Let's add our results next:

$$(0.15+0.35+1.50+5.00)= $7$

So $15$ pennies, $15$ dimes, $7$ quarters, and $20$ quarters is equivalent to $$7$ .
