Respuesta :

Her total price would be $42.51 for 13 gallons (8+5). To find out how much each gallon costs you divide $26.16/8 = $3.27 . You then multiply $3.27x5 = $16.35 . You take $16.35 and add that on to $26.16 & get $42.51

Answer:

Step-by-step explanation:

26.16/8 = $3.27 per gallon. 3.27x5= 16.35, so she has to pay $16.35 for an extra 5 gallons.
