James sold magazine subscriptions with three prices: $26, $19, $ 23. He sold 3 fewer of the $26 subscriptions than of the $19 subscriptions and sold a total of 32 subscriptions. If his total of sales amounted to $716, how many $23 subscriptions did James sell?
Ace Rent a Car charges a flat fee of $15 and $0.25 a mile for their cars. Acme Rent a Car charges a flat fee of $30 and $0.17 a mile for their cars. Use the following model to find out after how many miles Ace Rent a Car becomes more expensive than Acme Rent a Car. c= 15+0.25m Ace, c=30+0.17m Acme
Can someone please help me with these two problems?
15 + 0.25m > 30 + 0.17m.
0.25m - 0.17m > 30 - 15,
0.08m > 15,
m > 187.5 Miles.
