41 divided by 2 plus 31 divided by 4 equals to 28.225
Answer:
$C = 0.30(m) + 15
C is bill cost
m is number of minutes used
Step-by-step explanation:
In this question, we are asked to write an equation that estimates the bill cost of Maggie’s phone bills.
We proceed as follows;
Now, let’s try and find the base fee.
We can calculate this using her bill for September.
Mathematically;
Bill = (Cost per minute * total minutes) + Base fee
Here, $0.30 per minute for 120 minutes will yield a total of 120 * 0.3 = $36
This means the base fee would be $51-$36 = $15
Now let’s say the bill is $C, and the number of minutes used is m
Mathematically;
$C = 0.30(m) + 15
3.75 each, 6 friends, $20. 6 multiplied by 3.75 is 18.75. you can buy 5 sandwiches
Answer: exponential decay and 18%
Step-by-step explanation: Since what is in the parentheses is less than 1, it is exponential decay
Answer:3 * (n + 4) = 93
3n + 12 = 93
Subtract 12 to both sides:
3n = 81
Divide 3 to both sides:
n = 27
