She will spend $1475 to move into the apartment
Explanations:Cost of the apartment = $550 per month
To move in she will pay first and last month's rent and security deposit
Since the cost of rent is uniform for all the months:
Cost of first month's rent = $550
Cost of last month's rent = $550
Security deposit = $375
Total cost = (Cost of first month's rent) + (Cost of last month's rent) + (Security deposit
Total cost =550 + 550 + 375
Total cost = $1475
