Answer:
$1343
Step-by-step explanation:
After subtracting 15% from 100% of the original price, the price Mr. Quick paid is 85% of the original price.
0.85 × 1580 = 1343
Mr. Quick paid 1343 for his computer.
So what you should do is
15% off, then add tax or
2075 times 0.85 times 1.185=2090.04 about
you can't just add and subtract percents because they are percents of different things
what he did was
he found 15% of 2075 and 18.5% of 2075 then found the difference and added to 2075 to find his total
what he should have done is
found the discounted price (15% off) then found the tax on that
first way
2075 times 0.15=311.25
2075-311.25=1763.75
1763.75 times 0.185=326.29375
1763.75-326.29375=2090.04
2nd way (easy, if you understand commutative property and stuff)
100-15=85
1+0.185=1.185
2075*0.85*1.185=2090.04
answer should be $2090.04
(10,84)(20,159)
slope(m) = (159 - 84) / (20 - 10) = 75/10 = 7.5
y = mx + b
slope(m) = 7.5
use either of ur points...(10,84)...x = 10 and y = 84
now we sub and solve for b, the y int
84 = 7.5(10) + b
84 = 75 + b
84 - 75 = b
9 = b
so ur equation is : y = 7.5x + 9...with each shirt costing $ 7.50 and the one-time set up fee costing $ 9.00...with y being the total cost and x being the number of shirts bought
for 30 shirts......x = 30
y = 7.5(30) + 9
y = 225 + 9
y = 234 <== cost of an order of 30 shirts
Answer:

Step-by-step explanation:
Money to be spent is not more than $400.
Cost of a case of water = $7
Cost of each sandwich = $5
Let number of cases of water bought be 
Number of sandwiches bought be 
From the question we get

The inequality which would determine how many sandwiches, and how many cases of water that can be bought is
.
