Toko follows a budget to buy supplies to paint his room. He spends 1/2 of his budget on a roller, a tray, and tape. He spends $1

Natasha_Volkova [10]

The answer is $36.

B - budget
So the calculation is as following:
$B= \frac{1}{2}B + 12.27 + \frac{3.82}{ \frac{2}{3} } = \frac{1}{2}B + 12.27 + \frac{3.82*3}{2}= \frac{1}{2}B + 12.27 +5.73$
$B= \frac{1}{2} B + 18$
$B- \frac{1}{2}B = 18$
$\frac{1}{2}B = 18$
$B = 18*2=36$

Yuri [45]

Answer:

Step-by-step explanation:

3b + 2f = 17

2b + 4f = 18

-6b - 4f = -34

6b + 12f = 54

8f = 20

f = $2.50 fries

3b + 2(2.5) = 17

3b + 5 = 17

3b = 12

b = $4 burger

Given that f(x)=6x+2 and g(x)= 2x+4/5 solve for g(f(1))

kolbaska11 [484]

Note that f(1) = 6(1)+2 = 8. Next, evaluate g(x) at x=8: g(f(1)) = g(8) = 2(8) + 4/5, or 16 4/5.
