Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Derek wants to make scrapbooks with old family photos. An online scrapbooking company charges $10 for a basic book and $4 per page. Meanwhile, a family friend is willing to make a scrapbook for $43 plus $1 per page. For a certain number of pages, the price would be equal. How much would that cost? How many pages would that be?The scrapbook would cost $____ if it had ____ pages.
Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Derek wants to make scrapbooks with old family photos. An online scrapbooking company charges $10 for a basic book and $4 per page. Meanwhile, a family friend is willing to make a scrapbook for $43 plus $1 per page. For a certain number of pages, the price would be equal. How much would that cost? How many pages would that be?The scrapbook would cost $____ if it had ____ pages.
Define Variables: Let's define the variables.Let x represent the number of pages in the scrapbook.Let y represent the total cost of the scrapbook.
Write Equations: Write the equations based on the given information.For the online scrapbooking company: y=10+4x (since the basic book is $10 and each page is $4).For the family friend: y=43+x (since the basic book is $43 and each page is $1).
Set up System: Set up the system of equations.We have two equations:1) y=10+4x2) y=43+x
Solve by Substitution: Solve the system using substitution.Since both equations equal y, we can set them equal to each other to find the value of x:10+4x=43+x
Solve for x: Solve for x.Subtract x from both sides:10+4x−x=43+x−x10+3x=43
Isolate Variable Term: Subtract 10 from both sides to isolate the variable term.3x=43−103x=33
Calculate x: Divide both sides by 3 to solve for x. x=333 x=11
Substitute x: Substitute x back into one of the original equations to find y. Using the first equation: y=10+4xy=10+4(11)
Calculate y: Calculate the value of y.y=10+44y=54
Final Answer: Write the final answer.The scrapbook would cost $54 if it had 11 pages.
