please help with the 4 requirements thanks

Donovan Farms manufactures the bags of frozen french fries used at many restaurants. Last week, Donovan Farms purchased (transferred in from its polato farms) and used 101,000kg of potatoes at a price of $0.70 per kilogram. During the week, 2,150 direct labour hours were incurred in the plant at a rate of $12.45 per hour. The standard price per kilogram of potatoes is $0.85, and the standard direct labour rate is $12.15 per hour. Standards indicate that for the number of bags of frozen fries produced, the factory should have used 97,000kg of potatoes and 1,850 hours of direct labour. Requirements 1. Determine the direct materials price and efficiency variances. Be sure to label each variance as favourable or unfavourable. 2. Think of a plausible explanation for the variances found in Requirement 1. 3. Determine the direct labour price and efficiency variances. Be sure to label each variance as favourable or unfavourable. 4. Could the explanation for the labour variances be tied to the material variances? Explain. Requirement 1. Determine the direct materials price and efficiency variances. Be sure to label each variance as favourable or unfavourable. (Enter the results as positive numbers.)
