A lawn mower was originally priced at $450 but went on sale for 20% off. If Maurice bought the lawn mower and paid 5% sales tax, how much did he pay in for the lawn mower?

$378

Step-by-step explanation:

Full price:  1.00($450) = $450

20% off:     0.20($450) = $90

Sale price (after 20% off):  (1.00 - 0.20)($450) = 0.80($450) = $360

Final price, including tax:  (1.00 + 0.05)($360) = $378

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

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
