The only way i can think of working out this question is this:
t = time p = phone calls
insert what we know:-
93 = p + 50
make P on its own:-
take away 50 from each side
43 = p
switch (you don’t HAVE to do this) :-
p = 43
So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.
The correct answer is B) 9
Answer:
above is the answer to the question
Remember that when you are making stimates, you are going to roiund to the nearest dollar. Since $3.29 is closer to 3 dollars than four dollars, Sam should use the 3 dollars figure to estimate if he can afford 4 gallons of gas.
$3+$3+$3+$3=$12
The actual value is
![4(3.29)=13.16](https://tex.z-dn.net/?f=4%283.29%29%3D13.16)
, so $3 per gallon is indeed a god estimate.
We can conclude that the correct answer is: <span>
$3 + $3 + $3 + $3 = 12, so Sal can afford the gas.</span>
