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.
