Max charges $3.50 per hour when he mows lawns, plus $6.00 for transportation expenses. Which function rule represents the amount y Max charges to mow lawns for x hours?
y = 9.50x
y = 6.00x + 3.50
y = 3.50x + 6.00*****
y = 2.5x
The sale price of ground beef at a local grocery store is $1.49 for the first pound and $1.09 for each additional pound. Which function rule shows how the cost of ground beef, y, depends on the number of pounds, x
A y=1.49x+1.09
b y=1.09(x-1)+1.49
c y=(1.09+1.49)x
d y=1.09x+1.49*****
#1 looks good.
#2 is b because for all the additional pounds you add 1.09 except the first one so x-1 and the first pound is 1.49 so b but i don't know for sure on #1
(b) is correct.
only the extra pounds are $1.09
huh
@oof and any other who is confused
Basically...
What they are saying is number 1 is correct, which is C.
Number 2 is B. "Steve" and "pretty princess" explained why number 2 was incorrect.
The conversation was a bit all over the place...
1 is C
2 is B
thank you
To determine the function rule in each scenario, let's break down the given information and identify the variables involved.
For the first question:
Max charges $3.50 per hour of lawn mowing and an extra $6.00 for transportation expenses. The amount Max charges, y, is dependent on the number of hours, x.
Therefore, the function rule would be: y = 3.50x + 6.00
For the second question:
The cost of ground beef, y, depends on the number of pounds, x. The first pound costs $1.49, and each additional pound costs $1.09.
To calculate the cost, we need to subtract 1 from the number of pounds and multiply it by $1.09 since the first pound is already included.
Therefore, the function rule would be: y = 1.09(x-1) + 1.49.
Based on the explanation, the correct function rule for each scenario is as follows:
1. y = 3.50x + 6.00
2. y = 1.09x + 1.49
