Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. the customer wants the copy to have a length of 4.5 inches. each time he presses the reduce button on the copier, the copy is reduced by 12%. javier and his boss had an argument, because javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. his boss said that pressing the button 5 times would result in a length less than the desired 4.5 inches. which of the following conclusions can be made?

Javier should not press the button five time.

Step-by-step explanation:

The given scenario says that Javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. So, lets check that.

We will start at 8 inches.

Press once, inches.

Pressing again, we get inches.

Again pressing we get inches.

Again we get inches.

Again we get inches.

We can clearly see here that pressing 4 or 5 times does not get 4.5 inches exactly as claimed by Javier.

Therefore, Javier claim is not right and his boss is right.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the answer for this question is 38
