Mai, Clare, and Noah are making signs to advertise the school dance. It takes Mai 6 minutes to complete a sign, it takes Clare 8

Vaselesa [24]

Answer:

There is no question here, but suppose you want to find the number of signs they can make in half an hour, the answer is 14.

Step-by-step explanation:

Times it take to complete a sign.

Mai = 6 minutes

Clare = 8 minutes

Noah = 5 minutes.

Since they keep working for half an hour, which is 30 minutes. Suppose we want to find how many signs they can all make in that time, all we have to do is determine how many signs each person can make and then sum it.

Mai, who makes one every 6 minute, can make only 30/6 signs in 30 minutes. 30/6 = 5

Mai can make 5 signs in that time

Clare, who makes one every 8 minute, can make only 30/8 signs in 30 minutes. 30/8 = 3.75

She can only make 3 signs.

Noah, who makes one every 5 minute, can make only 30/5 signs in 30 minutes. 30/5 = 6

He can only make 6 signs.

In total, they can make 6 + 5 + 3 = 14 signs in half an hour.

Paul buys 5 bags of chips and 9 bags of pretzels for $16.95. Ian buys 1 bag of chips and 1 bag of pretzels for $2.55. Find the c

egoroff_w [7]

Answer: The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Step-by-step explanation:

Let x= Cost of one bag of chips

y= Cost of one bag of pretzels.

As per given, we have

5x+9y=16.95 ...(i)

x+y=2.55 ...(ii)

Multiply 5 to (ii), we get

5x+5y=12.75 ...(iii)

Eliminate (iii) from (i), we get

$4y=4.2\\\\\Rightarrow\ y=1.05$

Put value of y in (ii), we get

$x+1.05=2.55\\\\\Rightarrow\ x=2.55-1.05=1.5$

Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.
