Tuya spends $50 per week on groceries. He usually buys 5 oz. of his favorite cheese for $2/oz. and spends the other $40 on other goods. One week, the store has a sale on cheese that lowers the price to $1/oz. If Tuya buys 8 oz. of cheese and spends $42 on other goods at this new price, how much is his equivalent variation from this price change? (Select one.)

(a) More than $8: His consumption indicates that cheese is a luxury good.

(b) $8: This is how much money he would need to afford the new bundle at the old prices.

(c) Less than $8: His consumption indicates that cheese is a necessity good.

(d) Less than $8: He would substitute away from the new bundle at the old prices.

(e) Between $5 and $8: This is the substitution effect without the income effect.

(f) Between $5 and $8: This is the area under the demand curve between the two prices.

(g) $5: This is how much money he would need to afford the old bundle at the new prices.

(h) Less than $5: This is how much he would need to reach the old utility at the new prices.

(i) $0: His budget for groceries did not change so there is no equivalent variation.

(j) Uncertain: We would need to know his marginal rate of substitution to calculate this.
