krek1111 [17]

Kevin sold 10 pounds of apples and 20 pounds of raspberries.

Step-by-step explanation:

Given,

Cost per pound of apples = $3.50

Cost per pound of raspberries = $4

Total amount earned = $115

Let,

x represent the pounds of apples sold

y represent the pounds of raspberries sold

According to given statement;

3.50x+4y=115     Eqn 1

y = 2x                  Eqn 2

Putting value of y from Eqn 2 in Eqn 1

3.50x+4(2x)=115\\3.50x+8x=115\\11.50x=115

Dividing both sides by 11.50

\frac{11.50x}{11.50}=\frac{115}{11.50}\\x=10

Putting x=10 in Eqn 2

y=2(10)\\y=20

Kevin sold 10 pounds of apples and 20 pounds of raspberries.

Mariulka [41]

Answer:

  B, F

Step-by-step explanation:

The volume is the product of the dimensions:

  V = LWH

  V = (b^2)(3c^2)(2c^1) = (3·2)(b^2)(c^(2+1))

  V = 6b^2·c^3 . . . . . matches B

__

For b=3 and c=2, the volume is ...

  V = 6(3^2)(2^3) = 6(9)(8)

  V = 432 . . . . cubic inches . . . . matches F
