Answer: Amount of change : $30
percent increase : 200%
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Wholesale price: $15
</em>
- <em>Retail price: $45
</em>
To obtain the amount of change we have to subtract the wholesale price to the retail price:
Mathematically speaking:
45 -15 = $30
For the percent increase, the amount of change (30) is some percent of the original price (15). So:
30 / 15 =2 (decimal form)
If we multiply it by 100, the percentage is:
200%
A triangle's sum must add to 180 degrees. If two of the angles, summed, equal 50 degrees, then the vertex angle must equal 130 degrees. So, the vertex angle equals 130 degrees.
Answer:
93
Step-by-step explanation:
300-21= 279
279÷3= 93
<em><u>CHECK</u></em>
Thrice a number (93) added to 21 equals 300.
93×3= 279
279+21= 300

Answer:
For the first one is 340.
Step-by-step explanation:
The SA formula is SA = s^2 + 2 × s × l
so 10^2+2*10*12=340.
