The time required for a skilled worker to produce x shirts is given by the function t(x) = 4x + 2, where t is measured in hours. the salary the she is paid is given by the function s(t) = 15t, where s is measured in dollars.

a. if the worker produces 18 units, what will she be paid?

b. how many units would the worker need to produce to be paid $3,030?

A. $1,110

B. 50 units.

Step-by-step explanation:

A. Substitute into the function for calculate the time in hours required for the worker to produce 18 units:

Now you need to substitute into the function to calculate the amount in dollars she will be paid for 74 hours:

She will be paid $1,110.

B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute into the function and solve for T (to find the number of hours she requires to work to be paid $3,030)

Now, substitute into and solve for x, to calculate the number of units she produces in 202 hours:

She would need to produce 50 units to be paid $3,030

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
