Given:
Marc costs $29.75 a week to feed his dog
Determine how much does it cost him to feed his dogs for three weeks if the cost increased by 4.40 per week.
Solution:
The answer can be determined using logical analysis by adding the succeeding weeks.
1st week = $29.75 + $4.40
1st week = $34.15
2nd week = $34.15 + $4.40
2nd week = $38.55
3rd week = $38.55 + $4.40
3rd week = $42.95
=$34.15 + $38.55 + $42.95
= $115.65
Final answer:
= $115.65
