Answer:
Flashlight ; = $2.99
Water bottle = $1.50
Toothbrush = $1.29
Compass = $3.29
Step-by-step explanation:
Sales tax = 7%
Item: _____ price
Flashlight ; = $3.20
Water bottle = $1.61
Toothbrush = $1.38
Compass = $3.52
Total cost = price of item + sales tax
Sales tax = 7%
Total cost = (1 + 7%) * price of item
Total cost = (1 + 0.07) * price of item.
Total cost = 1.07* price
Flashlight = 1.07*1.29 = $3.20
Water bottle = 1.07*1.50 = $1.61
Toothbrush = 1.07*1.29 = $1.38
Compass = 1.07*3.29 = $3.52
Answer:
20 m
Step-by-step explanation:
Given:
- Length in mud = ¹/₂ its length
- Length in water = ¹/₃ its length
- Length above water = 3 ¹/₃ m
Let x be the length of the lamp post.
Convert 3 ¹/₃ to an improper fraction:
The total length of the lamp post (x) is the sum of the three given lengths:
Multiply both sides by 6:
Isolate x:
Therefore, the whole length of the post is 20 m.
