a.
tianjin
b.
wuhan
c.
nanjing
d.
beijing

Option C. Nanjing is the correct option.

Step-by-step explanation:

Jake is planning a trip to China. If we add expenses for all the cities then we get 557+681+595+728+449+534 = 3544, means Jake should have minimum 3544 yuan for the trip.

Unfortunately Jake has 2920 yuan available and he has to exclude one cheapest city from his trip.

Difference is 3544-2920 = 624 Therefore if he exclude Nanjing which has the expenditure of 681 yuan, his trip will remain under budget.

Option C. Nanjing is the answer.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
