Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Students in a health class are tracking how much water they consume each day. Melissa has two reusable water bottles: a small one and a large one. Yesterday, she drank 2 small bottles and 4 large bottles, for a total of 2,794 grams. The day before, she drank 1 small bottle and 4 large bottles, for a total of 2,411 grams. How much does each bottle hold?The small bottle holds _____ grams and the large one holds _____ grams.
Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Students in a health class are tracking how much water they consume each day. Melissa has two reusable water bottles: a small one and a large one. Yesterday, she drank 2 small bottles and 4 large bottles, for a total of 2,794 grams. The day before, she drank 1 small bottle and 4 large bottles, for a total of 2,411 grams. How much does each bottle hold?The small bottle holds _____ grams and the large one holds _____ grams.
Set up equations: Let's denote the amount of grams the small bottle holds as S and the large bottle as L. We can set up two equations based on the given information:1. For the first day: 2S+4L=2794 grams2. For the second day: 1S+4L=2411 grams
Use elimination method: To use elimination, we can multiply the second equation by 2 to align the coefficients of S with the first equation:2(1S+4L)=2×2411This gives us: 2S+8L=4822 grams
Subtract equations: Now we subtract the first equation from this new equation to eliminate S:(2S+8L)−(2S+4L)=4822−2794This simplifies to: 4L=2028 grams
Solve for L: We can now solve for L by dividing both sides by 4:44L=42028L=507 grams
Substitute back and solve for S: With the value of L known, we can substitute it back into either of the original equations to solve for S. We'll use the second equation:1S+4(507)=2411S+2028=2411
Final solution: Subtract 2028 from both sides to solve for S: S=2411−2028S=383 grams
