Answer:
sum will be 924.
formula for sum- n/2[a1+l]
F(x)=60+0,75x
Because she charges 60 per session, which will not change. And you don’t know how many miles she has to drive so that will be 0,75x.
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
<em><u>Solution:</u></em>
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
