Calvin works at a clothing store. He sells 3 pairs of jeans for $66.49 each, 2 shirts $28.99 each, and a belt for $15.40. He also gives a refund for a coat that a customer returned for $89.95. What is the net change in the amount of money for the store?

182 / 182.9

Step-by-step explanation:

199.47 +57.98 + 15.40 - 89.95    

3 x 66.49 = 199.47

2 x 28.99 = 57.98

since there was only one for the belt and the coat there is no problems for that.

add and subtract all of that and you get 182 or 182.9

i did the problem on my own and then checked it on a calculater. although if it isnt right im very sorry

70.30

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
