Julia pays a flat rate of $106 for her cell phone and is charged $0.12 for every text she sends. julia spends at least $142 on her phone bill each month. which of the following describes the number of texts she sends?
a. a minimum of 300
b. a maximum of300
c. more than 300
d. fewer than 300

a. A minimum of 300

Step-by-step explanation:

If her bill  is $142 then it is a sum of the flat rate plus the money she pays for all the smses she sent. As an equation, it can be expressed this way

106 + 0.12x = 142  where x  is the number of smses

0.12x = 36

x = 300 smses

So if we were told that she pays $142 per month, we'd know that she sends 300 smses. But we are told she pays AT LEAST $142 so there is a possibility that she sends even more than 300 smses

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

can i see the following ?
