It would be 1,602. Because if he pays 178$ every 4 months, you would divide 178 by 4 which is 44.50 then times it by 36 months which is 3yeara which gives you a total of 1602$
Order of operations is one way
MV =MegaVolt (1 MV = 1000000 V)
KV = KiloVolt (1 KV = 1000 V)
V = Volt (1V = 1 V) :))
mV = miliVolt (1V = 1000 mV)
μV = microVolt (1V) = 1000000 μV
The answer would be 5
-2+7=5
-2+7 is like 7-2
