It’s 15, 21, 28 because it’s going up 1,2,3 etc and adding one each time it goes up
Answer:
$5,376
$47,376
Step-by-step explanation:
Given :
Price of current model = $42,000
Percentage increase in price = 12.8%
Price increase in dollars :
12.8% of $42000
0.128 * $42000
= $5,376
Price of the next model :
Price of current model + increase in price
$42000 + $5376
= $47,376
Take away m from both sides to get 15=2m-9 and add 9 to get 24=2m, next divide by 2 to get m=12
The way to find the total number of pieces is to take the 2 and times it by 6 so the total will be 12 pieces
The final answer is b and c
