The cost for taking a taxi is $1.80 plus $0.10 per eighth of a mile. What is the cost of a ride that is 4.5 miles long?

the cost of the taxi will be $ 5.4

Step-by-step explanation:

given,

cost of taking taxi = $1.80 + $0.10 per eighth of a mile

to find the cost to travel 4.5 miles long

$0.10 per eighth of a miles means for 1/8 mile we will have to pay $0.10

for 4.5 mile we will be charged 4.5 * 8 * $0.10

= $ 3.6

so, cost of taking taxi = $1.80 + 4.5 * 8 * $0.10

= $1.80 + $ 3.6

= $ 5.4

hence, the cost of the taxi will be $ 5.4
