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 h
er 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
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
Use your complementary angles to solve for the missing angle. Remember a line is 180 degrees and any triangle whether its obtuse or acute it also equal 180.
