Answer:
Step-by-step explanation:
The 20% discount amounted to ...
0.20 × $42.00 = $8.40
so the price before tax was ...
$42.00 -8.40 = $33.60
The tax amount is 3% of this value, so is ...
0.03 × $33.60 = $1.008 ≈ $1.01
So the total price paid for the shirt was ...
$33.60 +1.01 = $34.61
Randy paid $34.61 for the shirt after discount and tax.
___
<em>Alternate solution</em>
You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...
$42.00×0.80×1.03 = $34.608 ≈ $34.61
Answer:
a) 1/24 do total
Step-by-step explanation:
We have that:
The total is 1.
The first friend gets 1/4 of the total.
The second friend gets 1/3 of the total
The third friend gets 3/8 of the total.
The remaining is x.
So
The least common multiple between 4, 3 and 8 is 24. So
So the correct answer is:
a) 1/24 do total
Answer:
6
Step-by-step explanation:
(x + 9) * (x - 2) = 60
x^2 - 2x + 9x - 18 = 60
x^2 + 7x - 18 = 60
x^2 + 7x = 78
FACTORING:
x(x + 7) = 78
x = 6
