Answer:

75 ≤ length < 85

Step-by-step explanation:

You know a number 5 or greater will round up to the next higher number in the number place to its left. Similarly, numbers less than 5 round down (get replaced by zero).

This means that 75 will round up to 80. and 84.9999... will round down to 80.

a) The lower bound on length is 75. The length must be at least 75.

b) The upper bound on length is 85. The length must be less than 85.

The price of an item has been reduced by 85% . The original price was $45. What is the price of the item now.

Kobotan [32]

Answer:the price for the item now it's 6.75

Step-by-step explanation:

Origin price is 45=100% after reduction comes to 85% =x

X stands for the unknown value of the reduction therefore

45=100%

X=85%

45*.85=100x

After calculation you realised the value of x reduction value it's 38.25

Hence, original price is 45 your less from the value reduced 38.25 therefore the value of the item is 6.75
