James went on a vacation and bought 8 meals for $10 each, 2 basketball tickets for $45 each, 2 baseball jerseys for $65each. Wri
inessss [21]
So 8 meals for $10 each , 2 tickets for $45 each, and 2 jerseys for $65 each
So (8x10) + (2x45) + (2x65) is the equation
And the answer is $300 because 8x10 is 80, 2x45 is 90, 2x65 is 130 and if you add it all up you'll get $300
80 + 90 = 170 + 130 = 300

Hope this helps! :)

By selling an article for $250, a man makes a profit of 25%. what was the cost price of the article.
pashok25 [27]

Answer:

200 dollars

Step-by-step explanation:

Let's say p equals the cost price of the article. Since the man made 25% profit, that means he got 100% of what he originally paid plus another 25% of what he originally paid. In other words, he sold the article for 125% of the original price. Converting that to a decimal we get:

250=p*1.25

Some simple division gets us a cost price of 200 dollars.
