I think the first option is correct because after taking away $28 from $50, you have $22 left over. If you know how gift cards work, then you know you cannot go over the limit ( the limit here is $22) so the “or equal to” is included. Moreover, because you can’t go over the limit with a gift card, the value of x would have to be less than or equal to $22. If you have any questions comment on my answer so I can answer them! Hope my answer helps!
Okay. To find the miles per gallon of B, we have to divide 100 by 2.6. 100/2.6 is 38.4615385 or about 38.5 miles per gallon when rounded to the nearest tenth. Car B goes approx. 38.5 miles per gallon.
