Last week at a festival, a man sold 5 times as many tie-dyed T-shirts as silk-screened shirts. He sold 228 shirts altogether.

kumpel [21]

Answer:

The man sold 190 tie-dyed T-shirts

Step-by-step explanation:

This problem can be modeled by a system of equations.

I am going to call x the number of tie-dyed T-shirts that the man sold and y the number of silk-screened shirts that he sold.

We have that he sold 5 times as many tie-dyed T-shirts as silk-screened shirts. So this gives us our equation 1)

1) x = 5y.

We also know that altogether, he sold 228 shirts. So this gives us our equation 2)

2) x + y = 228.

Now, we solve the system formed by equations 1) and 2)

x = 5y

x + 5y = 228

6y = 228

y = 38

x = 5*38

x = 190

So, in all, the man sold 190 tie-dyed T-shirts and 38 silk-screened T-shirts.

if your restaurant serves 50 bowls of French onion soup daily and each serving has 8 ounces of onion per portion. Do you think i

kirill [66]

The second option saves time and cleaning elements, so that one is better.

<h3>Which option is better?</h3>

We know that every day you sell a total of 50 bowls, and each one needs 8 oz of onion, this means that you need:

50*8 oz = 400 oz

So you need 400 ounces of onion per day.

If you buy at $1.99 per pound (1 lb = 16 oz)

Then the cost per ounce is:

c = $1.99/16

And the cost of 400 ounces is:

C = ($1.99/16)*400 = $49.75

In the case of the pre-sliced onions, the total cost would be:

C' = ($2.99/16)*400 = $74.75

So in the first case, each portion costs:

$49.75/50 = $0.995

And in the second case:

$74.75/50 =$1.495

So the extra cost is returned by the extra time and savings in cleaning elements, thus, the second option is better.

Wheel world sold 875 cars last year if the sales this year are 120% of sales last year how many cars will they sell this year

inn [45]

okay so first you wanna turn that 120% into a decimal and the decimal form of that would be 1.2 or 1.20

Secondly you want to multiply 875 by the 1.2

875*1.2 = 1050

So if they sell 120% of last years sales they will sell 1050 cars this year.

Hope this helped :)
