Two students were asked to graph the rational number -7.1. amy states that the number is between -8 and -7, but laura states that the point is between -7 and -6. how can you determine which student is correct?

Amy is correct, -7.1 is between -7 and -8.  We know this because in order for it to be in between -6 and -7, the number would have to be a decimal with a whole number of 6 (for example, 6.3 or 6.7).  But -7.1 has a whole number of 7 so it is in between -7 and -8

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
