I find it easiest to subtract and add the percentages to make a multiplier, then use that.
After the man's discount, he pays (100% - 12%) = 88% of the list price. After tax, he pays (100% + 3%) = 103% of the discounted price.
The amount he actually pays is $255×0.88×1.03 = $231.13.
The best choice is ...
(B) $231.13
Answer:
see explanation
Step-by-step explanation:
Expressing as equations
9x + 10y = 297 → (1) ← that is B
8x + 5y = 194 → (2) ← that is D
To solve the system of equations, multiply (2) by - 2
- 16x - 10y = - 388 → (3)
Add (1) and (3) term by term to eliminate the term in y
(9x - 16x) + (10y - 10y) = (297 - 388), that is
- 7x = - 91 ( divide both sides by - 7 )
x = 13
Substitute x = 13 into either of the 2 equations and solve for y
Using (1), then
(9 × 13) + 10y = 297
117 + 10y = 297 ( subtract 117 from both sides )
10y = 280 ( divide both sides by 10 )
y = 28

Cost of a large box of candy = $28
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given as:
y = mx + b; where m is the slope of the line and b is the y intercept (that is value of y at x = 0).
a) From the graph, we can see that the straight line touches the y axis at $100 in which the temperature is 0 degrees. Therefore the y intercept is:
(0, 100)
b) The slope of the line can be gotten by taking two points that the line passes through. Using the points (0, 100) and (12, 500):
The astroid is 100,000,000 miles away.
It's traveling at a speed of 100,000 miles per day.
100,000,000 ÷ 100,000 = 1,000
1,000 days.
The factors are 6 and x + 5
