A bride and groom both invited guests to their wedding. The bride invited twice as many women as the groom did, and the groom in

n200080 [17]

Answer:

option 1) 50

Step-by-step explanation:

Let m and w denote the men and women respectively.

From the question, if the groom invited w number of women, then bride invited 2w number of women.

Also, if the bride invited m number of men,then the groom invited 2m.

Hence we can write the following maths equation:

w+2m=105.........1

2w+m=135.........2

We multiply eqn(1) by 2 to get eqn(3)

This implies that,

2w+4m=210.......3

We then subtract eqn (2) from eqn(3) to obtain;

3m=75

we divide through by 3

$\implies \frac{3m}{3} = 75$

$\implies m= 25$

Substituting the value of m into eqn (1)

to find the value for w

$\implies w + 50 = 105$

subtracting 50 from both sides.

$\implies w + 50 - 50= 105 - 50$

$\implies w+2(25)=105$

$\implies w= 55$

So we can say the :

bride invited 25 men and 110 women,

groom invited 50 men and 55 women.

Chicken strips at a restaurant sell for the following prices: 4 pieces for $2.40 6 pieces for $3.00 How much do customers save p

const2013 [10]

Answer:

10 cents

Step-by-step explanation:

In order to answer this question we have to find how much each chicken strip costs individually.

Let's start with the 4 piece.

To find how much each piece costs we have to divide $2.40 by 4. Like this:

$\frac{2.40}{4} = .60$

In the 4 piece, every chicken strip costs .60 cents.

Now, let's do the 6 piece.

Like before we are going to divide $3.00 by 6.

$\frac{3.00}{6} = .50$

In the 6 piece, every chicken strip costs .50 cents.

Therefore, customers save 10 cents when they buy the larger quantity.

I hope this helps!

If you have any questions let me know!
