Can you please help me with this? I don't even know where to start
You need to take the estimate and add the VAT. Then take this total cost and divide it by 12 to solve for the monthly payment needed... (1450)(105/100)/12=126.875 Clearly, a monthly payment of 130 is enough to cover the yearly cost.
1450(1.05) = 1522.50...this is total with VAT included 1522.50 / 12 = 126.875...rounds to 127 per month so,yes....130 per month is enough
