Solve the problem.A vendor has learned that, by pricing pretzels at $1.00, sales will reach 159 pretzels per day. Raising the price to $2.00 will cause the sales to fall to 119 pretzels per day. Let y be the number of pretzels the vendor sells at x dollars each. Write a linear equation that models the number of pretzels sold per day when the price is x dollars each.
A. y = -40x + 199
B. y = - 
x + 
C. y = -40x - 199
D. y = 40x + 119
Solve the right triangle using the information given. Round answers to two decimal places, if necessary. 
a = 4, A = 30°; Find b, c, and B.
A. b = 6.93 c = 9 B = 70° B. b = 6.93 c = 9 B = 60° C. b = 6.93 c = 8 B = 60° D. b = 6.93 c = 8 B = 70°
