Randy's parents gave him an allowance of d dollars each month. One month, he put half of his allowance in the bank and then bought a book for $8. He had $12 left in his pocket after buying the book. Write an equation to solve for the amount of Randy's monthly allowance. Then, solve it.​

add 8 to the 12 and then multiply it by two

Step-by-step explanation:

8 + 12 = 20 * 2 = $40

one half = in the bank

other half = 8+12=20

so half of his allowance is 20dollars

allowance for a month = 20+20

=40

randy's monthly allowance is 40 dollars
