Inequalities
Chua pays a monthly fee of $25 for his phone service, plus $0.05 per minute of use.
Let M = number of minutes Chua uses the phone service.
His monthly cost for the phone service is:
C = 25 + 0.05M
The least he has been charged in a month is $89.40. If we want to know the number of minutes he used the service in that month, then we must solve the inequality:
25 + 0.05M ≥ 89.40
Subtracting 25:
0.05M ≥ 89.40 - 25
Operating:
0.05M ≥ 64.40
Dividing by 0.05:
M ≥ 64.40 / 0.05
M ≥ 1288
He has used his phone service at least for 1288 minutes in a month
I think the answer is 419%
just divide 33.52 by 8 and turn that decimal into a percent
Answer:
$471.60
Step-by-step explanation:
The double time rate is not specified in the question. But I will assume it's 2 times the normal rate. Therefore...
13.10 x 20 + 8 x (13.10 x 2)
Answer = $471.60
Answer:
It’s a way to show how things are related. It may be a mathematical pattern.
Step-by-step explanation:
Answer:
-32 and -33
Step-by-step explanation:
x + (x + 1) = -65
2x +1 = -65
2x = -66
x = -33. So (x + 1) = -33 + 1 = -32
-33 + -32 = -65
