Savannah and Reagan both work in a grocery store. They each stocked the same number of shelves last Saturday, but it took Reagan

less time. They've been told that they'll spend their entire 4-hour shifts next Saturday stocking shelves. If their average speeds are consistent, who will likely stock more shelves next Saturday?
HELP!

Answer:

Reagan

Explanation:

Since Reagan is able to stock the same number of shelves as Savannah while spending less time to do so, it means that Reagan is able to stock shelves faster than Savannah, thus Reagan is able to stock more shelves than Savannah given that their average speeds are constant and that they both work under 4-hour shifts.

Hope this helps :)

What is the step by step process of this question

Hello there!

In order to solve this system of equations, you would first need to make one equation have a negative variable.

2a + 3b = -1
(3a + 5b = -2) -1

2a + 3b = -1
-3a - 5b = 2

Now, we have to modify the equations for it to be able to cancel out a variable. To do this, you would need to look at the least common multiple.

2: 2, 4, 6, 8, 10
3: 3, 6, 9, 12, 15

One least common multiple would be 6 so let's modify the equation!

(2a + 3b = -1) 3
(-3a - 5b = 2) 2

6a + 9b = -3
-6a - 10b = 4

Now, let's cancel out the variable and solve for b.

9b = -3
-10b = 4

-1b = 1
b = -1

In order to solve for a, just plug in the b into one equation and solve for a.

2a + 3(-1) = -1
2a - 3 = -1
2a = 2
a = 1

The answer would be a = 1 and b = -1
