Eric's family is driving to Los Angeles. The total distance is 250 miles. First, they drive 123.7 miles and stop for lunch. Then they drive 64.4 miles and stop for gas. How many miles do they need to drive to complete their trip? What is a hidden question you need to answer to solve the problem?

Eric's family is driving to Los Angeles and the total distance to be covered is 250 miles

initially they travel 123.7 miles and then they stop for lunch

then again started their journey and drove 64.4 mile and then stop for gas

so the remaining distance to Los Angeles will be

= 250 - ( 123.7+64.4)

=250 - 188.1

= 61.9miles

The hidden question that needs be answered before reaching to the final answer is 'What is total distance they have travelled till reaching to gas station?'

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
