Question

A boy bought a painting book. $\$4$ more than three times the cost of a painting book is $\$58$. Find the cost of the painting book.

• A. $15$
• B. $17$
• C. $51$
• D. $18$

Answer 1

The correct option is D $18$

Let’s assume the cost of the painting book as “x”.
It’s given that $\$4$ more than three times the cost of the painting book is $\$58$.
$4+3y=58$
$3y=58-4$ (subtracting $4$ on both the sides)
$3y=54$
$y=18$ (dividing both the sides by $3$)

The cost of the painting book is $\$18$.

So, option D is correct.
