Answer:
$13,400
Step-by-step explanation:
<u>Given the following data;</u>
Tuition and book per year = $5,500
Transportation per month = $100
<u>In 2 years;</u>
Total tuition and book = $5,500 * 2 = $11,000
Total tuition and book cost = $11,000
Transportation;
There are 12 months in a year, in 2 years = 12 * 2 = 24 months.
Thus, total on transportation = $100 * 24 = $2,400
Total transportation cost = $2,400
Substituting into the above equation, we have;
Overall cost = $11,000 + $2,400
Overall cost = $13,400.
<em>Hence, Lakita's education will cost her $13,400 in total.</em>
