The original price is c.

discount of 5% => 5% less = c 5 / 100 = 0.05c

Then the grocery bill will be: c - 0.05c = 0.95 c.

You can also say since the beggining that 5% disscount implies 0.95 factor, which leads to c 0.95 = 0.95c.

Answer: 0.95c 

Answer:

\(y=c-0.05 c\)

Step-by-step explanation:

Cost of Sally's groceries = c

Since she has a discount card of 5 %

So, She get discount on amount c = \(5\% \times c\)

                                                         = \(\frac{5}{100}c\)

                                                         = \(0.05 c\)

So, she will get a discount of amount 0.05 c.

So, amount she need to pay = c-0.05 c

Hence ,the expression represents Sally’s grocery bill 'y': \(y=c-0.05 c\)
