To find the percent of error divide how off the wrong answer was by the right number, then multiply by 100.  
Bryan's guess of 730 was 120 less than the actual number so you would divide 120 by 850. 120/850 = 0.141  
Then we would multiply that by 100.  0.141 * 100 = 14.1  
His percent of error was 14.1%. The percent of error is negative since his guess was less than the right answer.

Kristin spent $120 on shirts. Dress shirts cost $40 and t-shirts cost $8. If she bought a total of 7 shirts, then how many of ea
FinnZ [79.3K]

Answer:

The correct answer is: She bought 2 dress shirts and 5 t-shirts

Step-by-step explanation:

Let's marked dress shirts with x and t-shirts with y.

Now we will make equations to solve this problem:

x + y = 7  =>  y = 7 - x

40 x + 8 y = 120

When we replace y = (7 - x) in the previous equation we get:

40 x + 8 (7 -x) = 120  40 x + 56 - 8 x = 120  => 32 x = 120 - 56 =>

32 x = 64  => x = 64/32 = 2 => x = 2

y = 7 - x = 7 - 2 = 5 =>  y = 5

x = 2 dress shirts

y = 5 t-shirts

God with you!!!
