Answer:
A =21
B=125
C=34
Step-by-step explanation:
Answer:
The slope is 1
Step-by-step explanation:
Lets pick two points on the line
(0,1) and (-1,0)
We can use the slope equation
m = (y2-y1)/(x2-x1)
= (0-1)/(-1 -0)
=-1/-1
=1
The total cost function is the sum of the two given functions, and this is equal to:
c(t) = 190 + 70*t
<h3>
How to find the linear function for the total cost?</h3>
We know that:
- The plumber charges p(t) = 115 + 25*t
- The electrician charges e(t) = 55*t + 75.
If she hires both of them for the same time t, then the total cost function will be given by the sum of the two above functions, we will get:
c(t) = p(t) + e(t)
c(t) = (115 + 25*t) + (55*t + 75)
c(t) = (115 + 75) + (55*t + 25*t)
c(t) = 190 + 70*t

Answer:
B
Step-by-step explanation:
it needs to be at least 6
Answer:
Ok:
Step-by-step explanation:
We know Josh buys 3 oranges for $2 and sells 2 oranges for $3. Let's take the LCM (least common multiple) of 2 and 3. It is 6. If he buys 6 oranges, he needs $4. When he sells 6 oranges he makes $9. That is a total profit of $5. In total that means, if we multiple by 10, that means that if he sells 60 oranges, he would make $50. Thus C is the answer
