The system of equations y = one-fourth x minus 1 and y = negative one-half x minus one-fourth is shown on the graph below.
On a coordinate plane, 2 lines intersect at (1, negative three-fourths).
What is a reasonable estimate for the solution?
Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
