<span>The answer is that
4 kg of pure tin and 28 kg of 4% tin alloy were used to produce the 16% alloy.
</span>
Let,
x
= kg of pure 100% tin
and y = kg of 4% tin
x
+ y = 32
x
= 32 -y
1.00 x + 0.04 y = 0.16 x 32
By
solving the above system of equations we find:
Now
put the value of x in the above equation;
1
x (32 - y) + 0.04 y = 5.12
32
– y + 0.04y = 5.12
y – 0.04y = 32 – 5.12
0.96y
= 26.88
y = 26.88/0.96
y = 28 kg of 4% tin
Now
put the value of y in x = 32 – y
x = 32 – 28
<span>x = 4 kg of pure 100% tin</span>
Answer:
Step-by-step explanation:
When you go shopping for anything, you know that the more of that something you buy, the more money you are going to spend. In other words, the amount of money you spend depends directly upon the amount of stuff you buy. So the number of boxes of cookies you buy is the independent variable and the amount of money you spend on the cookies is the dependent variable.
Based on the number of times that Caleb writes checks, uses his debit card, and uses the ATM, his monthly bank fees are $11 and $15.70 at NeoBank and Arbor Bank respectively.
<h3>What are Caleb's bank fees?</h3>
The question is incomplete so I will use a similar question to answer it.
Caleb's fees at Neobank would be:
= (12 checks x 0 per check) + (10 debt card uses x 0 per use) + (6 ATM uses x 1 per use) + 5 Monthly fee
= 0 + 0 + 6 + 5
= $11
Caleb's fees at Arbor Bank:
= (12 checks x 0.10 per check) + (10 debt card uses x 0.25 per use) + (6 ATM uses x 2 per use) + 0 Monthly fee
= $15.70
