First, find out how much will Gina pay for tuition by multiplying her number of credits by the cost per credit: 14 * 450 = $<<14*450=6300>>6300.
Then find out how much she pays for textbooks by multiplying the number of books by the cost per book: 5 * 120 = $<<5*120=600>>600.
Finally, add up all Gina's costs to find the total of 6300 + 600 + 200 = $<<6300+600+200=7100>>7100.
