The price of the bushel is 1.22, 1.41, 1.38, and 1.27.
To calculate the weighted average, all you need to is to just add all the values given above and then divide it by 4, since we only have 4 values of the bushel.
So: 1.22 + 1.41 + 1.38 + 1.27 = 5.28
5.28 / 4 = 1.32
Round it off to only two significant figures, you would get: $1.30.
Answer:
- trail mix: $1.25
- jelly beans: $3.50 per pound
Step-by-step explanation:
The difference between double the first purchase and the second purchase is $7 and 2 pounds of jelly beans. Hence a pound of jelly beans is $3.50.
(4t +8j) -2(2t +3j) = (33) -2(13) . . . . . let t and j represent pounds of trail mix and jelly beans, respectively
2j = 7 . . . . . . . . . . simplify
j = 7/2 = 3.50
Using that value in the first purchase, we get ...
2t +3(3.50) = 13
2t = 13 -10.50
t = 2.50/2 = 1.25
A pound of trail mix is $1.25.
Answer:
6.
Step-by-step explanation:
x/7 - 3/8 = 27/56
Multiply through by 56 , as 7 * 8 = 56 we have:
8x - 3*7 = 27
8x = 27 + 21 = 48
x = 6.

Answer:
<em>There are 72 crayons in the box</em>
Step-by-step explanation:
<u>Fractions</u>
To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.
Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:

From that portion, 65% are red, or equivalently, 35% are yellow.
We write 35% as a fraction:

Thus, the portion of yellow crayons is:

This fraction of x crayons is equal to 14, thus:

x = 72
