The regular price of a chair is $175.90. Find the sale price of the chair If the regular price is reduced by 10 %, and the new price is then reduced by 15%

$ 134.56

Step-by-step explanation:

Regular price = $175 .90

Reduction = 10% of 175.90

                 = 17.59

Price after reduction = 175.90 - 17.59 = $ 158.31

Second reduction = 15% of 158.31

                             = 0.15 * 158.31

                             = 23.7465

                             = $ 23.75

New price = 158.31 - 23.75

                  = $ 134.56

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
