The amount of pounds of fresh apples you need to pick in order to get 150 lb of dried apples is 200lb
If apples lose 75% of their weight during drying with a total of 150 lb of dried apples, then;
75% of x = 150
0.75x = 150
x = 150/0.75
x = 200lb
Hence the amount of pounds of fresh apples you need to pick in order to get 150 lb of dried apples is 200lb

A. Parasailing: $39; Horseback Riding: $48
B. Parasailing: $51; Horseback Riding: $30
C. Parasailing: $27; Horseback Riding: $46
D. Parasailing: $63; Horseback Riding: $24
Answer:
Horseback riding costs $30 and parasailing costs $51, so B.
Step-by-step explanation:
This is answered by using simultaneous equations, let x be parasailing and y be horseback riding.
3y + 2x = 192
2y + 3x = 213
Multiply each equation by the number in front of the y of the other equation:
2 x (3y + 2x = 192)
3 x (2y + 3x = 213)
Which results in:
6y + 4x = 384
6y + 9x = 639
Simply minus the two equations to get rid of the y:
6y - 6y = 0
4x - 9x = -5x
384 - 639 = -255
The negatives cancel out which give a result:
5x = 255
x =
x = 51
So parasailing costs $51
Now you can simply plug this value into one of the equations:
3y + (2 x 51) = 192
192 - 102 = 3y
90 = 3y
y =
y = 30
So horseback riding costs $30!
Hope this helps.
To increase a given amount by 22%, you should multiply the original amount by 1.22. This conversion results from adding the 22% increase to the 100% of the original amount, thus totaling 122%, or 1.22 when expressed in decimal form.
To increase an amount by 22%, you should multiply the original amount by 1.22. This is because the original amount is considered 100%, or 1 when we talk in decimal terms. To find a 22% increase, you add this percentage to the 100% of the original, making a total of 122%, which translates to multiplying by 1.22 in decimal.
For instance, if you have a value of 50 and you want to increase it by 22%, you multiply 50 by 1.22 (50*1.22 = 61). Therefore, a 22% increase of 50 is 61.

7x + 6
6 + 7 ÷ x
7 + 6x
Answer:
The right expression is 7x + 6
Step-by-step explanation:
From the question, it says 6 more than the product of 7 and a number.
Let the number multiplied by 7 be x.
Thus,
We are looking for the number that is 6 more than 7x.
From the options given, the only option that has a number 7x is option B. It also has the 6 more than 7x. Thus, the right answer is 7x + 6
