Michael can buy 4 sandwiches and 3 cups of coffee for $23.75. Amy can buy 2 sandwhiches and 5 cups of coffee for $19.75 how much
Kobotan [32]

Answer: The cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.

Step-by-step explanation:

Let x be the cost of one sandwich and y be the cost of one cup of coffee.

By considering the given situation, we have the following equations :-

4x+3y=23.75.................(1)\\\\2x+5y=19.75................(2)

Multiply 2 on both sides of equation (2) , we get

4x+10y=39.5................(3)

Subtract equation (1) from equation (3), we get

7y=15.75\\\\\Rightarrow\ y=\dfrac{15.75}{7}=2.25

Put value of y in (1), we get

4x+3(2.25)=23.75\\\\\Rightarrow\ 4x+6.75=23.75\\\\\Rightarrow\ 4x =17\\\\\Rightarrow\ x=4.25

Hence, the cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.

The Sognefjord is the deepest fjord in Norway at 1,308 metres (4,291 ft) If a submersible floating on the surface was to dive ve
natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is 1308-48=1260\ \text{m}

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

\dfrac{1263}{35}=36\ \text{minutes}

The time taken by the submersible to dive the required distance is 36 minutes.

Alchen [17]

Amount of money Aisha receive from selling all of the bracelets is $33.25.

<u>Step-by-step explanation:</u>

In this question, its given that Aisha made bracelets for a craft fair. She spent $29.75 on supplies to make the bracelets. Each bracelet cost her about $0.85 to make. Aisha sells each bracelet for $0.10 more than it cost her to make. Let's calculate Number of bracelets Aisha made as \frac{total-cost}{cost-of-one-bracelet}.

Number  = \frac{total-cost}{cost-of-one-bracelet}

⇒ Number  = \frac{total-cost}{cost-of-one-bracelet}

⇒ Number  = \frac{29.75}{0.85}

⇒ Number  = 35

Now , its given that Aisha sell these bracelets with $0.10 more then it cost her i.e. at $0.95 , Let's calculate selling price as :

Price = 0.95(35)

Price = $33.25

Therefore, amount of money Aisha receive from selling all of the bracelets is $33.25.
