Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.\newlineGrayson went to play miniature golf on Monday, when it cost $1\$1 to rent the club and ball, plus $6\$6 per game. Warren went Thursday, paying $1\$1 per game, plus rental fees of $16\$16. By coincidence, they played the same number of games for the same total cost. How much did each one spend? How many games did each one play?\newlineGrayson and Warren each spent $\$_____ and played _____ games.
  1. Define Variables: Let's define the variables:\newlineLet xx be the number of games played by both Grayson and Warren.\newlineLet yy be the total cost for both Grayson and Warren.\newlineNow, we can write the equations based on the given information:\newlineFor Grayson: y=$(1)(rental fee)+$(6)x(cost per game)y = \$(1) \text{(rental fee)} + \$(6)x \text{(cost per game)}\newlineFor Warren: y=$(16)(rental fee)+$(1)x(cost per game)y = \$(16) \text{(rental fee)} + \$(1)x \text{(cost per game)}
  2. Write Equations: We can now write the system of equations as follows:\newlineFor Grayson: y=6x+1y = 6x + 1\newlineFor Warren: y=x+16y = x + 16
  3. Set Equations Equal: To solve the system using substitution, we can set the two equations equal to each other since they both equal yy:6x+1=x+166x + 1 = x + 16
  4. Solve for x: Now, we solve for x:\newline6xx=1616x - x = 16 - 1\newline5x=155x = 15\newlinex=155x = \frac{15}{5}\newlinex=3x = 3
  5. Substitute xx: Now that we have the value of xx, we can substitute it back into one of the original equations to find yy. We'll use Grayson's equation:\newliney=6x+1y = 6x + 1\newliney=6(3)+1y = 6(3) + 1\newliney=18+1y = 18 + 1\newliney=19y = 19
  6. Final Results: We have found that xx, the number of games played, is 33, and yy, the total cost for both Grayson and Warren, is \(\(19\))\(. So, Grayson and Warren each spent \$(19) and played \)\(3\) games.
