Tara took a total of 45 quizzes over the course of 9 weeks. After attending 10 weeks of school this quarter, how many quizzes will Tara have taken in total? Assume the relationship is directly proportional.

After 10 weeks, Tara will have taken 50 quizzes.

Step-by-step explanation:

Given that Tara took a total of 45 quizzes during the 9-week course, to determine the number of quizzes she will take after 10 weeks, taking into account that it is a proportional relationship, the following calculation must be performed:

(45/9) x 10 = X

5 x 10 = X

50 = X

So, after 10 weeks, Tara will have taken 50 quizzes.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
