You don't multiply both of them, it's a coordinate function. There's suppose to be a comma in between
The answer is A....a=5 b=30
60% decrease
15 is 60% of 25
What is 60% of 25?
Y is 60% of 25
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 60% * 25
Converting percent to decimal:
p = 60%/100 = 0.6
Y = 0.6 * 25
Y = 15
Answer: x ≥ 1307
Explanation:
First, write the formula:
monthly fee: $14
minute rate: 7¢ or $0.07
total charge: $105.49
.07x + 14 ≥ 105.49 (the sign is this way because they said this price was the least she had been charged for a month.
You can solve for x just like you would in an equation by making the ≥ sign an equal sign
.07x + 14 = 105.49
- 14 -14
.07x = 91.49
÷ .07 ÷ .07
x = 1307 minutes
since you didn't divide by a negative number, the inequality sign stays the same:
x ≥ 1307
