Solution

The correct option is A $370
Given,

Fare for Flight 1 = $105

Fare for Flight 2 = $255

Estimating follow rules as given:

i. If the deciding digit < 5, then round down.

ii. If the deciding digit > 5, then round up.

iii. If the deciding digit = 5, then round up.

Total fare for both flights = Sum of fares of Flight 1 and Flight 2

= 105 + 255

Rounding the numbers to the nearest tens, we get:

= 110 + 260

Adding the rounded numbers, we get:
So, the estimated fare for both the tickets is $370.
