Mathematics
1 answer:
Charra [1.4K]3 years ago
6 0

Answer:

1.0282

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

Decrease of 3% followed by a 6% increase:

Calculate each multiplier, and then multiply then:

Decrease 3%: 1 - (3)/100 = 0.97

Increase 6%: 1 + (6)/100 = 1.06

0.97*1.06 = 1.0282

The answer is 1.0282

A school snack bar sells a mix of granola and raisins. The mix includes 2 pounds of granola for every 3 pounds of raisins. How m
kifflom [539]
The easiest way to solve a problem like this is to cross multiply and solve 

The problem gives us a ratio 
2 pounds of granola = 3 pounds of raisins 
which makes a ratio of \frac{2}{3}
The other ratio is 
? pounds of granola = 24 pounds of raisins
which makes a ratio of \frac{x}{24}

To solve, set them equal to each other ...
\frac{2}{3} =  \frac{x}{24}

Now we must cross multiply...
To cross multiply, we multiply 2 and 24 
and we multiply 3 and x 
Now we have an equation to solve!
3x = 48 
To solve and get your final answer, divide...
x = \frac{48}{3}

x = 16
You'll need 16 pounds of granola
