Step-by-step explanation:
im pretty sure this is correct but sorry if im wrong
2/3(120) = 240/3 = 80 do not drink
4/5(120) = 480/5 = 96 do not smoke
72 do not smoke or drink
96 - 72 = 24 do not smoke
80 - 72 = 8 do not drink
72 do not do either
120 - (24 + 8 + 72) = 120 - 104 = 16 drink and smoke
It is a bad estimate because the gap between 712 and 589 is clearly (if you were just estimating in hundreds) would be 200
200 would be a better guess
The Answer is -9/8 mark brainliest
Answer:
Step-by-step explanation:
Given that prices for a pair of shoes lie in the interval
[80,180] dollars.
Delivery fee 20% of price.
i.e. delivery fee will be in the interval [4, 9]
(1/20th of price)
Total cost= price of shoedelivery cost
Hence f(c) = c+c/20 = 21c/20
The domain of this function would be c lying between 80 to 180
So domain =[80,180]
---------------------------------
Amount to be repaid = 42 dollars
Once he received this amount, the price would be
105+42 =147
But since price range is only [21*80/20, 21*180/20]
=[84, 189]
Since now Albert has 147 dollars, he can afford is
[80,147]
