In this question, we're trying to find cost of one sandwich.
To find this, we must make a systems of equation from the given information:
We would represent sandwiches as "s" and drinks as "d".
Systems of equations:
6s + 4d = 53
4s + 6d = 47
Solve for s:
6(6s + 4d = 53)
-4(4s + 6d = 47)
36s + 24d = 318
-16s - 24d = -188
--------------------------
20s = 130
Divide both sides by s
s = 6.50
This means that one sandwich costs $6.50
Answer:
$6.50
Answer:
Penny needs 
cups of flour to make 3/4 of the recipe.
The recipe will make 18 cookies.
Step-by-step explanation:
We have been given that a recipe for oatmeal cookies makes 24 cookies. Penny wants to make 3/4 of the recipe.
To find the number of cookies that will 3/4 of the recipe will make, we need to find 3/4 of 24 as shown below:
Therefore, the recipe will make 18 cookies.
We are also told that recipe calls for 2 1/2 cups of flour. To find amount of flour needed for 3/4 of the recipe, we will multiply 2 1/2 cups by 3/4 as:
Therefore, Penny needs cups of flour to make 3/4 of the recipe.
