question 6/12

A text message can have a maximum of 160 characters. If Daisy has typed 3 sentences with 45

characters each, then which equation can be solved to find the number of characters she can still

type. Let "c" equal number of Daisy characters left.

c = 160 - 3 (45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3 * (45)

c = 160 - 135

c = 25
