For Labor Day, a furniture store is offering sale prices that "take 1/4 off" the regular price. Which of the following expressions could represent the sale price for furniture that has a regular price of c dollars? Select all that apply. (1/4)c (3/4)c c - 1/4 c + 1/4 c - (1/4)c

I believe the answer is c-1/4c and c-(1/4)c

Step-by-step explanation:

To find what 1/4 off (25% off) is, you multiply the regular price by 1/4, so that would be 1/4c OR (1/4)c.

Then you have to subtract the amount off from the regular price, so that would be c-1/4c OR c-(1/4)c

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

step-by-step explanation:

if x = 2 you have to find x to finish the problem
