Concept explainers
Who did correct calculation to get the correct answer, done by two girls while solving the value of variable a.
Answer to Problem 52HP
Both are not correct. Only Luna is correct as she got the correct answer by doing correct calculation.
Explanation of Solution
Given information: Two girls are finding the value of a so the line that passes through
Formula/Concept used: Rate per pound is actually the slope of the line that will be formed on joining these given dots. And slope of a line, from any two points, is calculated using the formula :
Slope of the line
Calculation: So, based on above formula, on plug in all given values in above formula, the correct steps to find the slope of this line should be:
On cross multiply:
Conclusion: It is observed that Luna did the calculation in the same way, as did above and got the correct answer as
