Trey can drive his car 130 miles on 4 gallons of gas. At this rate, if gas cost $ 3.45 per gallon how much will it cost to drive 260 miles?
and then you....here let me show you...
cost
-----
miles
set this up:
13.8 x
---- = ---
130 260
13.8 represents cost of 4 gallons, so you basically put the cost over ur miles. FIRST u cross multiply, so u multiply 13.8 * 260 and then 130*x
it will look like this:
3588= 130x
u divide 3588/130
when you divide you get the answer 27.6.
My answer is 27.6 :)
thats mean
Trey's car gets 32.5 miles per gallon.
He drives 260 miles.
260 / 32.5 = 8 gallons
8 * $3.45 = $27.60 to drive 260 miles.
We got he same answer, HI, but in different ways.
