Answer:
a) $170
b) 12
Step-by-step explanation:
A = 250 - 20t
where A is Jina's account balance and t is the number of trips she takes.
a) If Jina takes 4 trips, then t = 4.
Substitute t = 4 into the given equation:
A = 250 - (20 x 4)
= 250 - 80
= 170
So Jina has $170 left in her account after 4 trips.
b) The calculate the maximum number of trips Jina can take without running out of money, set A to zero and solve for t:
when A=0: 0 = 250 - 20t
Add 20t to both sides: 20t = 250
Divide both sides by 20: t = 12.5
Therefore, Jina can take 12.5 trips. However, she can't take a half-trip so we should round the number down to 12 trips (as after 12 trips she will only have enough money left for half a trip).
So, the largest number of trips Jina can take without running out of money is 12.

Answer:
17.27 or 17.267
Step-by-step explanation:
To simply this, you just divide the numerator and denominator by its GCF (Greatest common factor)
Factors of 18 : 1,2,3,6,9,18
Factors of 30 : 1,2,3,5,6,10,15,30
As you can see, the great common factors of 18 and 30 is 6.
So divide 18 by 6 and 30 by 6, and you get 3 and 5
