pls answer the following question, thanks!

A consumer who loves chocolate has a budget of $10 and out of that income purchase chocolate x and a composite good y. The price of the composite good is $1. The consumer's utility 1 function is U(x,y) = 2 5+}! so that MUx = E and MUy =1 a. Suppose the price of chocolate is initially $0.50 per ounce. How many ounces of chocolate and how many units of the composite good are in the consumer's optimal basket? b. Suppose the price of chocolate drops to $0.20 per ounce. How many ounces of chocolate and how many units of the composite good are in the optimal basket? c. Compute the income and substitution effects that result from the decline in the price of chocolate. Illustrate the effects in a graph
