how to do the question below using the formula

(g) elasticity = [(new eoq - old eoq)/old eoq x 100] / [(new sales - old sales)/ olds sales x 100]

is this the formula to use to find the elasticity of EOQ with respected sales?

(h) elasticity = [(new eoq - old eoq)/old eoq x 100] / [(new carrying cost - old carrying cost)/ old carrying cost x 100]

Annual Sales is 300,000 units. The carrying cost is 20% of the purchase price; The purchase price is RM25 per unit; The ordering cost is RM1,500 per order; The desired safety stock level 8,000 units; The delivery time is 1 week (7days). g) What would happen to the EOQ if annual sales doubled (all other unit costs and safety stocks remain constant)? What is the elasticity of EOQ with respect to sales? (That is, the percentage change in EOQ divided by the percentage change in sales). h) If carrying costs double, what will happen to the EOQ level? (Assume the original sales level of 300,000 units). What is the elasticity of EOQ with respect to carrying costs? (That is, the percentage change in EOQ divided by the percentage change in carrying costs). Annual Sales is 300,000 units.
