Answer:47(whatever the unit is square)
Step-by-step explanation:
Answer:
Slope = 40
Step-by-step explanation:
Time spent = 70 hours(given)
Fixed charge = $75 (given)
x = Total number of hours (given)
Variable charge = $40 * Total number of hours.
Variable charge = $40x
Fee charged, y = Variable charge + Fixed charge
y = 40x + 75 ($)
The equation of a straight line is given as: y = mx + c
where m = slope
Comparing it with the equation above, m = 40
For every
, we have

So, negletting the first term, each term of the sum is greater than 1, which implies

Which means that the series diverges.
You can use 27 $10 bills which gets your at a total of $270 then you can use 1 $5 bill so now you're at $275 then you can use 4 $1 bills that gets you at your total of $279. The least number of bills you can use is 32.
