Question 1181759: United Express, a national package delivery service, charges a base price for overnight delivery of packages weighing 1 pound or less and a surcharge for each additional pound. A customer is billed $25.80 for shipping a 7-pound package and $64.55 for a 32-pound package.
Find the base price and the surcharge for each additional pound. Answer by ikleyn(52756) (Show Source):
It is quite obvious.
To find the surcharge for each additional pound, divide the difference in charges
$64.55 - $25.80 by the difference in weights (32 - 7 ) pounds
the surcharge = = 1.55 dollars per pound.
Next, find the base price for the 1st pound by subtracting 6*1.55 from $25.80 dollars
the base price = 25.80 - 6*1.55 = 16.50 dollars.
