Answer:
49.73
Step-by-step explanation:
You make the fractions into decimals and get 9.5 and 7.3. Then multiply those by the price given to get $23.75 and 25.98. When you add those numbers together you get $49.73.
For the linear system :
r+t = 20 and 5(r+t) = 150
If you sub in the first equation into the second, you will get: 100 = 150, which is incorrect
It means the system does NOT have solutions.
