Astudent has earned the following scores on four 100-point tests this marking period: 63, 72, 88, and 91. what score must the student earn on the fifth and final 100-point test of the marking period to earn an averagetest grade of 80 for the five tests?

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!
