X+9 ? I'm not sure if that was the kind of answer you were looking for but that's what I got out of that.
Answer:
Precent Increase
Step-by-step explanation:
Well, we can find the answer by multiplying the two fractions. 3/4*1/8 equals 3/32.
If the cost increases $0.90 every three years , then the cost increases $0.30 per year. the slope will be 0.3/1 or just 0.3
12x2= $24
24+28+45= $97
So $97 is 100%
So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)
97 x 0.7 = $67.90
