a local gas station uses the formula c= 0.635L+ 6.25 to charge customers who want to buy gasoline and a car wash
what is the total cost if you buy 20L of gasoline?
please help!
Plug in 20 in place of L (which represents the number of litres bought) and solve for C, using the formula provided.
C = 0.635*20 + 6.25 = ___?
$125?
To find the total cost when buying 20L of gasoline, we need to substitute the value of 20L into the given formula c = 0.635L + 6.25.
So, let's do the calculation:
c = 0.635(20) + 6.25
c = 12.7 + 6.25
c = 18.95
Therefore, the total cost of buying 20L of gasoline is $18.95.
