Let n = number
"3 times the sum of a number and 7" translates to 3(n + 7)
"2 less than five times the number" translates to 5n - 2
The word "is" becomes the equals sign.
3(n + 7) = 5n - 2
I think you already asked this one.

EXPLANATION
Answer:
$70 each
Step-by-step explanation:
If 4 friends each buy a hat, that would be $50 because that is $12.50X4=%50.00. Then, Since the total is $190 and $50 is off the chart, you would be left with $140 to spend on two t-shirts. Finally, since they are the same price, you divide $140/2=$70. Each t-shirt is $70.
