Final answer:

Khalil's equation: 4s + 3b = 11.67
Ronda's equation: 8s + 1b = 12.89
Using the elimination method, we find that the price of one can of soup is $1.35 and the price of one loaf of bread is $2.09.

Step-by-step explanation:

a. Let's say the price of one can of soup is 's' dollars and the price of one loaf of bread is 'b' dollars.

For Khalil's purchase, he buys 4 cans of soup and 3 loaves of bread, which costs $11.67. So we can write the equation: 4s + 3b = 11.67.

For Ronda's purchase, she buys 8 cans of soup and 1 loaf of bread, which costs $12.89. So we can write the equation: 8s + 1b = 12.89.

b. To solve the system of equations, we can use the substitution method or the elimination method. Let's use the elimination method:

Multiplying the first equation by 8 and the second equation by 4, we get:

32s + 24b = 93.36

32s + 4b = 51.56

Subtracting the second equation from the first equation, we get:

20b = 41.8

b = 2.09

Substituting the value of 'b' back into one of the original equations, we can solve for 's':

4s + 3(2.09) = 11.67

4s + 6.27 = 11.67

4s = 5.4

s = 1.35

Therefore, the price of one can of soup is $1.35 and the price of one loaf of bread is $2.09.

Answer:

a) cblo

2)$3.44

Step-by-step explanation:

4 cans and 3 loaves=11.67

8 cans and 1 loaf= 12.89.

Set up equation:

x=cans

y=loaves


4x+3y=11.67\\8x+y=12.89 This is the answer for question A.

Multiply eq1 by 2:


8x+6y=23.34

Subtract eq3 by eq2:


5y=10.45\\y=2.09

Substitute:


8x+2.09=12.89\\8x=10.8\\x=1.35

One can of soup and one loaf of bread=


1.35+2.09 or 3.44

So:


$3.44

Hope this helps :D Please hit the crown if u can !!
