Cost of computer = money she earns pr week * number of weeks + discount
300 $ = 20 $ * weeks + 80$
(300 $ - 80$)/20$ = 11 weeks

Given b(x) = X+41, what is b(-10)?<br> О -10<br> боооо
ch4aika [34]
Answer: 31
step by step solution: so the function is b(x)=x+41. they want to know what the function would equal when b(-10). so b(-10) means that you would plug (-10) in for x in the function so the function would now be b(x)=(-10)+41. now all you have to do is simplify the function. b(x)=31. so the function b(-10)=x+41 equals 31. hope this helped!!! have a great day.
