Answer:
The price went up by 8.77%
Step-by-step explanation:
Let
57 cents be "old value" and 62 cents be the "new value"
<em><u>Percentage increase is always given by:</u></em>
Percentage Increase = ![\frac{new-old}{old}*100](https://tex.z-dn.net/?f=%5Cfrac%7Bnew-old%7D%7Bold%7D%2A100)
<em>Substituting these values into the formula gives us:</em>
![\frac{new-old}{old}*100\\=\frac{62-57}{57}*100\\=0.0877*100\\=8.77](https://tex.z-dn.net/?f=%5Cfrac%7Bnew-old%7D%7Bold%7D%2A100%5C%5C%3D%5Cfrac%7B62-57%7D%7B57%7D%2A100%5C%5C%3D0.0877%2A100%5C%5C%3D8.77)
Hence the price went up by 8.77%

Answer:
1434.375
Step-by-step explanation:
If you multiply 1,800 by 25% you get 1,350
you take 1,350 and add 6.25% because the 6.25% is the tax.
Then you will get 1434.37 or 1434.40
1 necklace will therefore cost 34/4 = $8.5
Step-by-step explanation:
She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.
At an average, she spent $49.
The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.
Thus $49 - $15 = amount spent on the 4 necklaces = $34.
4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5
Answer:1.7
Step-by-step explanation:
First you want to multiply 2.97 by 106
2.97 x 106 = 314.82
Now you want to multiply 1.72 by 107
1.72 x 107 = 184.04
Now you want to divide them
314.82 / 184.04 = 1.71
Now you want to round it to the nearest tenth... if a number is 5 or above you round it up but if it is 4 or below your number stays the same
Since 1 is lower than 5 you keep your number the same
<u>1.7</u>
