Question

Riley has (8p + 7) one-dollar coins and (2p + 5) one-dollars bills. Pam has 7p dollars fewer than Riley. a. How much money does Pam have? Give your answer in terms of p. b. If p = 6, how much money will Pam have after she gives half of her money to Riley? help me please

Answer 1

Riley has a total of,
                                 8p + 7 + 2p + 5  or
                                        10p + 12 dollars
Pam on the other hand has 
                                    (10p + 12) - 7p = 3p + 12 dollars
After giving half of this money to Riley, Pam will have
                                        1.5p + 6 dollars
