Since the store is offering a 30% discount, the sale price S will be equal to 70% of the list price L. We can represent this mathematically as:

S = 0.7L

Therefore, the correct choice is C).

A Store Is Offering a 30% Discount on All Items S=−0.7L\mathrm { S } = - 0.7 LS=−0.7L

A Store Is Offering a 30% Discount on All Items $\mathrm { S } = - 0.7 L$
