Answer:
They are taking 12 2 credit courses
The are taking 4 1 credit courses
Step-by-step explanation:
x = 1 credit courses
y = 2 credit courses
The number of courses is 16
x+y = 16
The number of credits is 28 so multiply the course by the number of credits
1x+2y=28
Subtract the first equation from the second equation
x+2y =28
-x-y=-16
-----------------
y = 12
They are taking 12 2 credit courses
We still need to find the 1 credit courses
x+y = 16
x+12= 16
Subtract 12 from each side
x-12-12 = 16-12
x =4
The are taking 4 1 credit courses
To convert square feet to square yards divide 9 by the number of square feet (I remember that since there are 3 feet in 1 yard and 9 is 3 squared) so 90/9=10. Multiply the 10 sq yds by the price per sq yd: 10x11=120. It would cost $120 :) I hope this helps :)
