Answer:
C. $945
Step-by-step explanation:
Cost of 1 cellular bill = (number of text msgs per day) x (cost per text msg) x (number of days in billing period)
in this case, it is given that :
cost per text msg = $0.89
number of texts per day = 22 or 23
billing cycle = 6 weeks = 6 x 7 = 42 days
hence,
Cost of 1 cellular bill = (22 or 23) x $0.89 x 42 days
if she sends 22 messages,
Cost of 1 cellular bill = (22) x $0.89 x 42 days= $822.36
if she sends 23 messages,
Cost of 1 cellular bill = (2) x $0.89 x 42 days= $859.74
if we compare thse 2 numbers that we have calculated with the choices, the closest match would be C. $945. The rest are just too far away in comparison.
