The number of books she would have completed in one day will be 2 books.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Given that:-

Emily completed reading 24/3 books in 32/4 days

Emily completed 8 books in 4 days. The number of the books will be calculated by using the expression below:-

4 days = 8 books

1 day = 8 / 4 = 2 books

Therefore the number of books she would have completed in one day will be 2 books.

Aldo’s coffee shop makes a blend that is a mixture of two types of coffee.Type A coffee costs 5.6 per pound. Type B costs 4.05 p

Pie

Answer: 93

Step-by-step explanation: $\\$ Since 160 cups of blend are sold , this means

$\\$ A + B = 160

$\\$ Since Type A is sold for 5.6 per pound , that means the total number of A sold = 5.6A

$\\$ Also , Type B is sold for 4.05 per pound , the total number of B sold = 4.05B

$\\$ And it was given that the total cost of blend = 751.85 , then

5.6A + 4.05B = 751.85

$\\$ A + B = 160 ............................. eqn 1

$\\$ 5.6A + 4.05B = 751.85 ..................... eqn II

$\\$ From eqn I , A = 160 - B ................ eqn III

$\\$ Substitute A = 160 - B into equation II , then we have:

$\\$ 5.6(160 - B) + 4.05B = 751.85

$\\$ Expanding , we have

$\\$ 896 - 5.6B + 4.05B = 751.85

$\\$ 896 - 1.55B = 751.85

$\\$ collecting the like terms

$\\$ 1.55B = 896 - 751.85

$\\$ 1.55B = 144.15

$\\$ Therefore B = 144.15/1.55

$\\$ B = 93

The Wellbuilt Company produces two types of wood chippers, economy and deluxe. The deluxe model requires 3 hours to assemble and

seropon [69]

Answer:

The maximum profit is reached with 4 deluxe units and 6 economy units.

Step-by-step explanation:

This is a linear programming problem.

We have to optimize a function (maximize profits). This function is given by:

$P=98D+72E$

being D: number of deluxe units, and E: number of economy units.

The restrictions are:

- Assembly hours: $3D+2E\leq24$

- Paint hours: $0.5D+1E\leq8$

Also, both quantities have to be positive:

$D\geq 0\\\\E\geq0$

We can solve graphically, but we can evaluate the points (D,E) where 2 or more restrictions are saturated (we know that one of this points we will have the maximum profit)

$(8;0) \rightarrow P=98*8+72*0= 784\\\\(0;8) \rightarrow P= 98*0+72*8=576\\\\(4;6) \rightarrow P=98*4+72*6=824$

The maximum profit is reached with 4 deluxe units and 6 economy units.
