Answer:
An expression represents the amount Kyle has in his savings at the end of the 14 months is 14d+1440
Step-by-step explanation:
Kayla saves amount per month = d
Kayla saves amount in 14 months = 14d
For 6 months, Kyle added an additional 20% of his $1,200 monthly earnings to his savings account
Additional amount per month= 20% of 1200 = [tex]\frac{20}{100} \times 1200=240[/tex]
Additional amount 6 months= [tex]240 \times 6 =1440[/tex]
Amount in account after 14 months = 14d+1440
Hence An expression represents the amount Kyle has in his savings at the end of the 14 months is 14d+1440
