What is the answer I’ve been so stumped.......
Dmitrij [34]

Answer:

229 Miles.

Step-by-step explanation:

Take the base fee of $18.99 and subtract it from the total amount.

$218.22 - $18.99 = $199.23

So he Deshaun has $199.23 in miles driven.

So take 199.23 and divide it by 87 cents, Since that is the extra charge for every mile.

199.23 / 87 = 229

Deshaun Drove 229 miles

Hope this helps!

Scotts cap holds 3 ounces so 192/3 = 64

Nikkis cap holds 4 ounces so 192/4 = 48

64-48 = 16 more caps for Scott
