Step-by-step explanation:
3/5 is the probability answer
Grocery store:
price per bottle = 13.80/12 = $1.15 per bottle
Convenience store:
price per botttle = 11.80/10 = $1.18 per bottle
The <u>grocery store is cheaper</u>, as the cost per bottle is lower.
So, looking at how many seniors there are, you can see that there are 35 of them. 25 are in sports, 5 are in music/drama, and 5 work. If you added them altogether, you get 35. Now, the chance of them being in sports is 25/35 chance/probability. You can simplify 25/35 because both of them are divisible by 5. 5 times 5= 25 and 7 times 5=35. Therefore, the answer is 5/7.
1). 1 3/5 + 2 4/5 = 4 2/5 or 4.4
2). 3/8 ÷ 2 2/5 = 5/32 or 0.15625
