Answer: y should be in the interval (0.4, 4)
Explanation:
The binomial 5y - 7 is in the interval (-5, 13) if and only if
-5 < 5y - 7 < 13
Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that
2 < 5y < 20
Then, we divide both sides by 5 to get the following inequalities
0.4 < y < 4
Hence y should be in the open interval (0.4, 4).
Answer:
I think it is $3.25
Step-by-step explanation:
<u>140*3=420- </u>original price with 140 sold each day
130*3.25=422.5- 10 less hotdogs sold with $0.25 price increase
110*3.75=412.5- 30 less hotdogs sold with $0.75 price increase
90*4.25=391.5- 50 less hotdogs sold with $1.25 price increase
60*5.75=345-80 less hotdogs sold with $2.75 price increase
