A. $ 1.50 B. $ 3.00 C. $ 4.00 D. $ 5.50 E. $ 7.00 On scanning the options, only option A will give a total amount less than 7.35$.i.e 1.5+5.5=7. Rest of the options will give an amount greater than 7.35$ and that's impossible given the total cost of sandwich and coffee inclusive of tax is 7.35$. Hence A.

A. $ 1.50 B. $ 3.00 C. $ 4.00 D. $ 5.50 E. $ 7.00 We can let c = the price of a cup of coffee and s = the price of a sandwich and create the following equation: s = 4 + c We are also given that the price of a sandwich and cup of coffee is $7.35, including a 5% sales tax. Thus: 1.05(c + s) = 7.35 c + s = 7.35/1.05 = 7 Thus, excluding the 5% sales tax, c + s = 7. Finally, we can substitute 4 + c for s in the equation c + s = 7 and we have: c + 4 + c = 7 2c = 3 c = $1.50 Answer: A

A. $ 1.50 B. $ 3.00 C. $ 4.00 D. $ 5.50 E. $ 7.00 \(s + c = 7.00\) ( Ex S.tax ) Now, \(s = c + 4\) Or, \(( c + 4 ) + c = 7\) Or, \(2c = 3\) Or, \(c = 1.5\) Thus, price of a cup of coffee, EXCLUDING the sales tax is $ 1.50 , answer will be (A) $ 1.50
