Step-by-step explanation:
a)
well, it is kind of written already :
228 miles and 6 gallons.

b)
it is not mentioned, but I guess we have to assume that he got the same miles/gallon ratio on this trip as well.
so, again
38 miles/gallon
and he used 9 gallons.
so, he drove 38×9 = 342 miles
Use P to represent the number of purses that Aisha has. 1/2P x 3 if P= 12 then 1/2 (12) x 3= 18
System 1 and system 3, because the second equation in system 3 is obtained by adding the first equation in system 1 to three times the second equation in system 1.
