Question

the age and hourly pay of five employees at a store are shown in the table. a line of best fit for the data is y = 0.9x - 4.5, where x represents age, in years, and y represents hourly pay, in dollars. based on the data, what is the best prediction for the hourly pay of a 25 - year - old? a. $17.50 b. $18.00 c. $19.00 d. $22.50 e. $32.78

Explanation:

Step1: Identify the values of x and the formula

We are given that $x = 25$ (age) and the formula for hourly - pay is $y=0.9x - 4.5$.

Step2: Substitute x into the formula

Substitute $x = 25$ into $y = 0.9x-4.5$. So, $y=0.9\times25 - 4.5$.

Step3: Calculate the multiplication part first

$0.9\times25=22.5$. Then the expression becomes $y = 22.5-4.5$.

Step4: Calculate the subtraction

$22.5−4.5 = 18$.

Answer:

B. $18.00$
