Read the passage.
the dirt was orange, striped in places where crumbs had slipped through the cracks when mami swept. papi had left a few boards down the center of the room and around his and mami's bed, to stand on until the ground was swept and flattened. mami was afraid to come into the house. there were small holes in the dirt, holes where snakes and scorpions hid. she turned swiftly and threw herself off balance so that she skipped toward the kitchen shed.

which inference is correct?

a) mami doesn't want to lose her balance

b) she is afraid of snakes and scorpions (i think it's this one but not sure)

c) mami is high and mighty

d) mami is embarrassed by the crumbs left behind after sweeping

in the problem you wrote said that the taxi charges $0.070 per mile(which would be 7 cents per mile), but then in your suggested equation you have it as $0.70 per mile (which is 70 cents per mile).

the latter seems more realistic, so i will assume that the taxi costs $5.00 and charges $0.70 per mile with tolls costing an additional $3.50. and it asks you to find how far you can travel on $36.50.

let x the number of miles traveled. since the taxi charges $0.70 per mile, multiplying this by the miles traveled (x) will yield the cost of the taxi ride as far as how far it took you. then adding this amount to the cost of the taxi ($5.00) and the additional cost for the tolls ($3.50) will give you the total cost of the taxi ride ($36.50)

that is,

            (0.70)x + 5.00 + 3.50 = 36.50

adding the like terms on the left-hand side of this equation, we arrive at the following:

            (0.70)x + 8.50 = 36.50

subtracting 8.50 from both sides of the equation, we get:

            (0.70)x = 28.00

to solve for x, divide both sides of the equation above by the coefficient of x (that being, 0.70):

            x = 40

thus, you can travel up to 40 miles on $36.50
