Design = $45
rate per child = $5.50
number of children, x
total cost, f(x) = $5.5x + $45
Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Answer:
4.1 calls
Step-by-step explanation:
The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:

Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:

Rounding to the nearest tenth, Roger will get about 4.1 calls.
