Answer:
Week and a day
Step-by-step explanation:
You have $30, you save $5 each week and your aunt gives you an extra $10. Equaling out to $15 per week. Since the bike costs $155.75, you subtract your $30, coming out to 125.75 then you divide it by 15 which is 8 days
Answer:
Third week = 23.35 miles
Step-by-step explanation:
First week total miles = 15 miles
he would like to run 30% more miles each week than the week before
Second week = 15 miles + (30% of 15 miles)
= 15 + (30% * 15)
= 15 + (0.3 * 15)
= 15 + 4.5
= 19.5 miles
Second week = 19.5 miles
Third week = 19.5 miles + (30% of 19.5 miles)
= 19.5 + (30% * 19.5)
= 19.5 + (0.3 * 19.5)
= 19.5 + (5.85)
= 23.35 miles
Third week = 23.35 miles
