Question

An airport parking lot charges a basic fee if $2 plus $1 per half hour parked. what is the total charge from parking in the lot for 72 hours? a. $144b.$146c.$75d.$72

Answer 1

Basic fee for parking is $2 + $1 per half hour parked

If the fee $1 for half and hour, this means they'll fee $2 for parking one hour.

Let x be the number of hours, the total cost for parking in the irport will be:

C=2+2x

C repreents the total cost.

Now replace x=72 in the expresion:

C=2+2*72= $146

The total charge for 72 hours parking is $146
