7Over the years, the river has been the source of a number of problems. In the nineteenth century, Londoners dumped waste from their homes into the Thames. This
made the water so smelly that the House of Commons had to relocate for a time. The
pollution of the river also contributed to an outbreak of disease that killed many
people and to the disappearance of most of the river's fish. Luckily, various clean-up
efforts during the twentieth century have greatly improved the river's water quality
and allowed fish to return.
What would be the BEST way to show people how the quality of the river's water has improved since the nineteenth century?

A) read an excerpt from one of Edmund Spenser's poems about the beauty of
the river

B) examine how the Thames River was described by playwrights during the
time of Shakespeare
C) demonstrate how there are greater toxins in the Thames today than in past
centuries
D) describe the increase in fish in the river since the clean-up efforts in the twentieth century

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

the answer is sail boat won the race , and it was going 8 feet per   second

the answer is b. i read this story before.
