Here's the whole thing +extras that are after
a.
f = total cab fare
m = distance travelled
f = 2 + 0.50m
b.
7.50 = 2 + 0.50m
c.
7.50 = 2 + 0.50m
7.50 - 2 = 0.50m
5.50 = 0.50m
5.50/0.50 = m
m = 11
Sara traveled 11 miles.
d.
f = 2 + 0.50m
f = 2 + 0.50 x 10
f = 2 + 5
f = 7
When the cab fare is over $7.00 on the holidays, $1 is discounted off the fare.
e.
Yes, Lupe traveled more than 10 miles. (refer to calculations used in c.)
