the number of ink cartridges bought, then the total cost, C, is modeled by
a. C= 100x + 35
b. C = 35x + 100
c. C= 100 + 35 + x
d. C= 100x + 35x

Respuesta :

Answer:

100 + 35x

Explanation:

Given the following

Initial cost of phone = $100

Monthly payment = $35

Payment after x months minus initial cosst = 35 * x = 35x

Total money after x-months = Initial payment + Payment after x months

Total money after x-months = 100 + 35x

wehre x is the number of months

Hence the required expression will be 100 + 35x
