I am weighed on scales which have a 10% error, that is, the scales show me 10% heavier than my real weight. If I actually weigh
stiks02 [169]
Remember you said the scale shows you 10% heavier.

So that's an increase of 10%

So value = 10% + 100% = 110%

So scale would show  110% of 82

110% of 82

= (110/100)  * 82

= 1.1 * 82

= 90.2

OR

We can simply find 10% of 82 and add it to the original 82.

10% of 82

(10/100) * 82

0.1 * 82 = 8.2

8.2 + 82 = 90.2    Same answer as before.

So scale shows 90.2 kg.

Ann increased the quantities of all the ingredients in a recipe by 60\%60%60, percent. She used 808080 grams (\text{g})(g)left p
kari74 [83]

Answer:

50 grams

Step-by-step explanation:

Let the amount of cheese required by the recipe be "x"

Ann increased 60% from original amount and then used up 80 grams. Thus:

<em>Original, increased by 60%, became 80</em>

<em />

This translated to algebraic equation would be:

x + 0.6x = 80

<u>Note:</u>  60% = 60/100 = 0.6

So we can solve the above equation for "x" and get our answer. Shown below:

x + 0.6x = 80\\1.6x=80\\x=\frac{80}{1.6}\\x=50

Hence,

the recipe required 50 grams of cheese
