MPM 10: Academic Mathematics Pasquale's cell phone plan charges him monthly using the relation y = 0.25x+20, where y is the
total monthly bill and x is the number of minutes he used for the month.
(a) Which variable is independent and which is dependent?
(b) How do you know the relation is linear?
Determine the rate of change in his monthly bill.
(d) What does the rate of change mean?
How does the rate of change relate to the equation?
When will his cell phone bill reach $1000?

3.76%

step-by-step explanation:

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
