Mary purchased 4 tires by mail order. She paid $54.90 per tire plus $6.50 per tire for shipping and handling. There is no sales tax, because the tires were purchased out of state. She also had to pay $8.34 per tire for mounting and balancing. At a local store, Mary's total for the 4 tires with mounting and balancing would be $332 plus 8% sales tax. How much did Mary save by purchasing the tires through the mail? Mary saved $ nothing on the purchase of 4 tires.

79.6 dollars saved

Step-by-step explanation:

Mail

4 times 54.90 equals 219.6

4 times 6.50 equals 26

4 times 8.34 equals 33.36

219.6 + 26 + 33.36 = 278.96

Local store

332 times .08 equals 26.56

332 + 26.56 = 358.56

Difference

358.56 - 278.96 = 79.6

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
