Q. Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.\newlineDylan and Leo are hosting events that are catered by the same company. Dylan plans to have 8787 adults and 9696 children attend, so the total projected cost of his meals is $4,938\$4,938. Leo has 7070 adults and 9696 children on his guest list, so he will pay the caterer $4,292\$4,292. How much does the caterer charge for each meal?\newlineEvery adult's meal costs $\$_____, and every child's meal costs $\$_____.
  1. Define Meal Costs: Let's denote the cost of an adult's meal as aa and the cost of a child's meal as cc. We need to find the values of aa and cc.
  2. Equation for Dylan's Event: Dylan's event has 8787 adults and 9696 children, and the total cost is $4,938\$4,938. This gives us the equation:\newline87a+96c=493887a + 96c = 4938
  3. Equation for Leo's Event: Leo's event has 7070 adults and 9696 children, and the total cost is $4,292\$4,292. This gives us the equation:\newline70a+96c=429270a + 96c = 4292
  4. System of Equations: We now have a system of two equations:\newline11) 87a+96c=493887a + 96c = 4938\newline22) 70a+96c=429270a + 96c = 4292\newlineWe can solve this system using the method of elimination or substitution. Let's use elimination.
  5. Elimination Method: Subtract the second equation from the first to eliminate cc:(87a+96c)(70a+96c)=49384292(87a + 96c) - (70a + 96c) = 4938 - 429217a=64617a = 646
  6. Solve for 'a': Divide both sides of the equation by 1717 to solve for 'a':\newline17a17=64617\frac{17a}{17} = \frac{646}{17}\newlinea=38a = 38
  7. Substitute 'a' into Equation: Now that we have the value for 'a', we can substitute it back into one of the original equations to solve for 'c'. Let's use the second equation:\newline70a+96c=429270a + 96c = 4292\newline70(38)+96c=429270(38) + 96c = 4292
  8. Calculate Adults' Total Cost: Multiply 7070 by 3838 to find the total cost for the adults at Leo's event:\newline70×38=266070 \times 38 = 2660
  9. Calculate Children's Total Cost: Subtract the cost for the adults from the total cost to find the total cost for the children at Leo's event: 42922660=16324292 - 2660 = 1632
  10. Calculate Cost per Child: Now, divide the total cost for the children by the number of children to find the cost per child's meal: 1632/96=171632 / 96 = 17 c=17c = 17
