c. $132.70
d. $263.25

The answer is:

d) $263.25

Step-by-step explanation:

John Davis worked a total of 27 hours. You get that by adding the number of hours he worked throughout the week together:

4+6+5+5+7 = 27

Then, you simply multiply his hourly earnings by the number of hours he worked:

9.75 x 27 = 263.25

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
