3) they will have the same solution because the first equation of system B is obtained by adding the first equation of system a
to 4 times the second equation of system a
4) The value of X for system a Will be equal to the value of Y for system b because the first equation of system b is obtained by adding -4 to the first equation of system a and the second equation are identical

Answer:
firm deposit is $1667.50
Step-by-step explanation:
given data
buys 12 file = $140
time = 90 days
interest = 3%
solution
we get here return on money over 90 day period is
we know Return on 360 days = 3%
return on money over 90 day = 3% ÷ 4 = 0.75%
we consider here required amount = x
so
$140 × 12 = x (1+0.0075)
x =
x = 1667.50
so firm deposit is $1667.50
