B represents a function ✔️
Answer:
$0.45
Step-by-step explanation:
ratio is 2:4:3
total is 9
270 ÷ 9 = 30
smoll
60 × 0.25 = $15
med
120 × 0.30 = $36
Big
91.50 - 15 - 36 = 40.5
40.5 ÷ 90 = $0.45
A simple way to turn this into an equation is by replacing the words with letters:
1464B = 3/4 S
Then you have to remove the 3/4 from the right side of the equation. You can do this by dividing both sides by 3/4:
1464 / 3/4 = S
Then you have to do the sum:
1464
/ 3
= 0488
488
X 4
= 1952
