$7

Step-by-step explanation:

Hello

I think  I can help you with that

we need to find a expression that show us the cost  of travel in taxi

Step 1

Let

C = total cost

A= standing charge

B= additional charge= $0.50* Km traveled

let x= km traveled

B=0.50*X

Now, we have the equation

C=A+0.50X

Step 2

replace

C=$3.00+$0.5x

she traveled  8 Km, hence

C=$3.00+$0.5(8)

C=$3.00+$4

C=$7

Jenny had to pay $7

have a great day
