Bill and his friends went to red robin. their order consisted of 2 hamburgers t $5.49 each, a chicken sandwich for $6.25, an order of ribs for $12.99, and 4 sodas at $1.75 each. they paid a 7% sales tax, and a 20% tip. how much money did lunch cost them?

Please mark brainliest! This was hard!

Answer $39.75

Explanation: $5.49 (hamburgers) x 2 = $10.98

chicken sandwich is $6.25 and ribs are $12.99

$1.75 (sodas) x 4 = 7

$10.98 + $12.99 + $7 = $30.97

7 percent tax is $2.16 so $30.97 + $2.16 = $33.13

20 percent of $33.13 is $6.62 so $33.13 + $6.62 = $39.75

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

c(x)= 6x + 3
