A phone company offers two monthly plans. Plan A costs $11 plus an additional $0.11 for each minute of calls. Plan B costs $27 p
irina1246 [14]

Solution:

Let x represent a number of calling minutes. According to the problem, we want:

11\text{ + 0.11 x = }27\text{ + 0.07 x}

now, putting the similar terms together, we obtain:

0.11\text{ x - 0.07 x = 27 -11 }

this is equivalent to:

0.04x\text{ = 16}

now, solving for x, we get:

x\text{ = }\frac{16}{0.04}\text{ = 400}

then, the correct answer for the first question is:

400 minutes is the number of minutes the two plans cost the same

now, for the second question, we can replace the above value (400 minutes) into the following equation:

11\text{ + 0.11(400) = }55

so that, the correct answer for the second question is:

$55 is the cost when the two plans cost the same

In logarithm, inverse operations are applied.
log_3{14} = log_3{7} + log_3{14} \\ log_3{14} = 0.631 + 1.771 \\log_3{14} = 2.402
