Answer:
Andy will spend 14.7 dollars and Emily will spend 21.3 dollars for the wire they need.
Step-by-step explanation:
We need to convert the lengths of the wire that Andy and Emily need from feet and yards to inches, since the table shows the cost per inch. We can use the following formulas to do the conversions:
1 foot = 12 inches
1 yard = 36 inches
Using these formulas, we can calculate the lengths of the wire in inches as follows:
Andy’s length in inches = 22 feet x 12 inches/foot = 264 inches
Emily’s length in inches = 11 yards x 36 inches/yard = 396 inches
Now, we can use the table to find the cost of the wire for each length. The table shows that the cost of the wire is given by the equation:
y = 0.05x + 1.5
Where y is the cost in dollars and x is the length in inches. Substituting the values of x for Andy and Emily, we get:
Andy’s cost = 0.05 x 264 + 1.5 = 14.7 dollars
Emily’s cost = 0.05 x 396 + 1.5 = 21.3 dollars
