Two airplanes are carrying food and medical supplies to a country in need. One airplane is carrying 63 meals and 57 medical kits. The total cost for those supplies on that airplane is $714. The other airplane is carrying 78 meals and 57 medical kits. The total cost for the supplies on that airplane is $789. Write and algebraically solve a system of linear equations to find the price of one meal.

63m + 57k = 714 (1)

78m + 57k = 789 (2)

The price of one meal is $5

Step-by-step explanation:

Let the price of one meal be m.

Let the price of one medical kit be k.

One airplane is carrying 63 meals and 57 medical kits and the total cost for those supplies on that airplane is $714.

This means that:

63m + 57k = 714 (1)

The other airplane is carrying 78 meals and 57 medical kits and the total cost for the supplies on that airplane is $789.

This means that:

78m + 57k = 789 (2)

We now a system containing two linear equations that can be used to solve to problem:

63m + 57k = 714 (1)

78m + 57k = 789 (2)

To find the price of one meal, we subtract equation (1) from (2) and simplify:

 78m + 57k = 789

- 63m + 57k = 714 _

  15m  = 75

=> m = 75 / 15 = $5

The price of one meal is $5

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
