Please solve and explain your solution. Thanks.

Marvin has a Cobb-Douglas utility function, U=q10.5g20.5 his income is Y=$300, and initially he faces prices of p1=$4 and p2=$1. If p1 increases from $4 to $5, what are his compensating variation (CV), change in consumer surplus (4CS), and equivalent variation (EV)? Marvin's compensating variation (CV) is $ (Enter your response rounded to two decimal places and include a minus sign if necessary.) Marvin's change in consumer surplus (ACS) is (Enter your response rounded to two decimal places and include a minus sign if necessary.) Marvin's equivalent variation (EV) is $ (Enter your response rounded to two decimal places and include a minus sign if necessary.)
