A hotel manager is making identical hospitality bags for guests using 75 soap bars 45 bottles of lotion and 62 bottles of shampo
charle [14.2K]

This question was not written properly

Complete Question

A hotel manager is making identical hospitality bags for guests using 75 soap bars 45 bottles of lotion and 65 bottles of shampoo what is the greatest number of identical hospitality bags the manager can make with the least amount of items left over

Answer:

The greatest number of identical hospitality bags the manager can make is 5

With each bag containing:

15 soap bars

9 bottles of lotion

13 bottles of shampoo

Step-by-step explanation:

We solve this question using Greatest Common Factor Method

We find the factors of 45, 65 and 75

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 65 are: 1, 5, 13, 65

The factors of 75 are: 1, 3, 5, 15, 25, 75

Then the greatest common factor is 5.

Therefore, the greatest number of identical hospitality bags the manager can make is 5

And each bag would contain

For soap bars

75 soap bars/ 5 hospitality bags

= 15 soap bars

For bottles of lotion

45 bottles of lotion / 5 hospitality bags = 9 bottles of lotion

For bottles of shampoo

65 bottles of shampoo/5 hospitality bags

= 13 bottles of shampoo

Jimmy has studied 22 hours over the last 10 days for the ACT. He studied either 2 hours a day or 3 hours a day. During the 10 da
Usimov [2.4K]

Let x represent the # of 2-hour days and y the # of 3-hour days. Jimmy's study was spread over 10 days. Thus, x + y must sum up to 10. Also, 2x + 3y must sum up to 22 hours.Our system now looks like this:


x + y = 10

2x + 3y = 22


Multiply the first equation by -2: -2x - 2y = -20 Add the 2nd equation to this:


-2x - 2y = -20

2x + 3y = 22

------------------ y = 2 So Jimmy had 2 3-hour study days and 8 2-hour study days.

Note how these figures add up to 22: 6 + 16 = 22

Hope that help!

La madre de rosita se ha comprado una mascarilla por un valor de 1 25 dolares al mismo tiempo se ha comprado un paquete de jabon
grandymaker [24]

Answer:

La cantidad inicial que tenía la madre de Rosita antes, comprando los artículos es de $13.90

Step-by-step explanation:

La información dada son;

El valor de la máscara = $ 1.25

El valor del paquete de jabones = $ 2.00

El valor del gel de alcohol = $ 3.00

La cantidad que le quedaba después de pagar = $ 7.65

Por lo tanto, tenemos;

La cantidad inicial que tenía la madre de Rosita antes, comprando los artículos = La cantidad que le quedaba después de pagar + El valor del gel de alcohol + El valor del paquete de jabones + El valor de la mascarilla

Por lo tanto;

La cantidad inicial que tenía la madre de Rosita antes, comprando los artículos = $ 7.65 + $ 3.00 + $ 2.00 + $ 1.25 = $ 13.90.
