<h3>
Answer: 98%</h3>
==================================================
Explanation:
The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.
85% of $900 = 0.85*900 = 765
After the 15% discount is applied, the customer would pay $765
---------
Then after the sale, the price is marked up by 15%
This means we'll multiply by 1.15 to indicate a 15% increase
1.15*765 = 879.75
Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.
---------
Afterwards, divide the value 879.75 over the original price of $900
879.75/900 = 0.9775
Move the decimal point two spots to the right to end up with 97.75%
That percentage rounds to 98% when rounding to the nearest whole percent.
Answer: y = 10x+14 (choice A)
===================================
Work Shown:
y = 7(x+2)+3x
y = 7x+7*2+3x ..... distribute
y = 7x+14+3x
y = (7x+3x)+14
y = 10x+14
This is in y = mx+b form with m = 10 as the slope and b = 14 as the y intercept.
Answer:
<em>41 degrees</em>
Step-by-step explanation:
<em>According to Angle Sum Property, the sum of the internal angles of a triangle is equal to 180 degrees.</em>
<em>Therefore,</em>
<em>52 + 87 + ? = 180</em>
<em>139 + ? = 180</em>
<em>? = 180 - 139</em>
<em>? = 41 degrees</em>
Answer:
Step-by-step explanation:
3.4x - 2y
Putting values of x and y in the equation
3.4(1) - 2(-2)
= 3.4 + 4
= 7.4
