The given statement written in symbolic language is x = 3y + 4 and x + y = 72 where "x" is the cost of one book and "y" is the cost of another book
Solution:
Given that Bruce bought two books
One book costs $ 4.00 more than three times the other
Let the two books be denoted as Book A and book B
Let "x" be the cost of book A
Let "y" be the cost of Book B
From given,
One book costs $ 4.00 more than three times the other
Let Cost of book A = $ 4.00 more than three times the other book B
x = 4 + 3 times cost of Book B
x = 4 + 3y
x = 3y + 4 --- (i)
Also given that Together, the two books cost him $72
cost of book A + cost of Book B = 72
x + y = 72 ------- (ii)
Therefore the given statement written in symbolic language is:
x = 3y + 4 and x + y = 72
