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.)
