Question

Two communication companies offer calling plans. With company x it cost $.30 to connect and then $.05 for each minute with company why it cost $.20 to connect and $.04 each minute. Simplify an expression that represents how much more company x charges incense for n minutes

Answer 1

Explanation:

m = number of minutes

x(m) = 0.05m + 0.3

y(m) = 0.04m + 0.2

to find the difference between both company plans we need to subtract y from x :

0.05m + 0.3 - (0.04m + 0.2) =

= 0.05m + 0.3 - 0.04m - 0.2 =

= 0.01m + 0.1

company x charges for n minutes

$0.01n + $0.1

more.
