Contractor a estimated a job would cost $54,000 to complete in 90 days. contractor b estimated he could complete the same job for $49,500 in 120 days. how much per day does each contractor charge

Contractor A estimated a job would cost $54,000 to complete in 90 days.

Per day charge of Contractor A = $54,000 / 90 = $ 600 / day

Contractor B estimated he could complete the same job for $49,500 in 120 days.

Per day charge of Contractor A = $49,500 / 90 = $ 412.50 / day

Therefore, Contractor A charges $ 600 per day and contractor B charges $412.50 per day.

Hope it helps..!!

Thank You :)

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
