Question

Before starting her job, Rosa had been on an airplane 10 times. Since then, she

has flown 12 times each year.
Let y represent the number of years since Rosa started her job and f represent
the total number of times she has flown.
Complete the table using the function f 12y + 10.
Y
1
3
5
7
f
46

Answer 1

f = 12y + 3

Explanation:

The equation to reflect this condition is:

• f = 12y + 10

Where

• 12 - is constant, the initial number of flights
• 10 - coefficient, number of flights per year
• y- number of years
• f- total number of flights

Answer 2

Before starting her job, Rosa flew on an airplane 10 times, which means when y = 0, f = 10.

Using the function f = 12y + 10, we can find the total number of times she has flown for different values of y:

When y = 1:

f = 12(1) + 10 = 22

When y = 3:

f = 12(3) + 10 = 46

When y = 5:

f = 12(5) + 10 = 70

When y = 7:

f = 12(7) + 10 = 94

Completing the table:

Y 1 3 5 7

f 22 46 70 94
