Ferry Chemical uses a standard cost system to account for the costs of its production of Chemical X$.$ Standards are $1\mathrm{.}5$ gallons of materials at $$105$ per gallon and $10$ hours of labor at a standard wage rate of $$11.$ During September, Ferry Chemical produced $2,600$ gallons of Chemical X$.$ Ferry Chemical purchased and used totaled $3,560$ gallons at a total cost of $$381,180.$ Payroll totaled $$302,730$ for $25,430$ hours worked. Calculate the following variances:

i$.$ direct materials price variance

ii$.$ direct materials quantity variance

iii. direct materials total $($spending$)$ variance

iv$.$ direct labor rate variance

v$.$ direct labor efficiency variance

vi$.$ direct labor total $($spending$)$ variance
