Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
2.25*x=10
Which x is the number of books purchased
Solve for x
X=10÷2.25
X=4.44
180/135=133.33
Therefore the answer is B; 33.33%
Hope this helps!
