Answer:

About 34 workers

Step-by-step explanation:

200/30 to find on average how many trees can be carved by one worker

The answer is 6.666, so just 6

Then 6*4=24 to figure out how many more trees can be carved by (4 more) workers

So, add 4 to 30 and about 224 trees can be carved.

Find points from graph.

Point (-5, 0)

Point (-9, -8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-8-0}{-9+5}$
[Fraction] Subtract/Add: $\displaystyle m=\frac{-8}{-4}$

Bill wants to rent a car.Rental Company A charges $35 per day plus $0.10 per mile driven.Rental Company B charges $25 per day pl

zlopas [31]

Answer:

m = 200 miles

Step-by-step explanation:

Rental Co. A: A(m) = $35 + ($0.10/mile)(m), where m is the number of miles driven

Rental Co. B: B(m) = $25 + ($0.15/mile)(m)

Set these two dollar amounts equal to each other and solve for m:

$25 + ($0.15/mile)m = $35 + ($0.10/mile)(m). Combine like terms, obtaining:

($0.05/mile)m = $10; then m = ($10) / ($0.05/mile), or 200 miles.

The price charged by the two companies would be the same when the car has been driven 200 miles.
