Hank is mowing lawns to earn enough to buy a $1400 computer. After 4 weeks, he has earned $340. What is the least number of full weeks he must work to be able to purchase his computer? Your answer should be a whole number.

12-13 weeks

Step-by-step explanation:

1 week of work is $85

$1400 - $340 = $1060

$1060 / $85 = 12.47

round it up and its 13 (or not then its 12)

normally you would round down, but i think it would make more sense to round up in this situation

answer: .75 km

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
