3) marvin bought a t shirt that was on sale for 20% off. he paid $14.21. for the t-shirt including
sales tax of 11 percent. use this information to answer questions a and b.
a circle the equation that can be used to find the original price of the t-shirt.
(c - 20c) +.11(e - 200) – 14.21
. 11(x - 20c) = 14.21
11(22.81 - 20(14.21)) = c
116.80c) + (c - 20c) = 14.21
b. solve the equation and interpret the solution

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
