Question 218473
Let C = the number of customers and T = the average temperature. The equation of variation can be written as:
{{{C = k/T}}} To find the value of k, the contant of variation, substitute C = 160 and T = 40.
{{{160 = k/40}}} Multiply both sides by 40.
{{{6400 = k}} so you can write:
{{{C = 6400/T}}} Now substitute T = 25 for today's average temperature.
{{{C = 6400/25}}} Evaluate.
{{{highlight(C = 256)}}}
Carol can expect 256 customers.
