6(15) + 10b > = 200
90 + 10b > = 200
10b > = 200 - 90
10b > = 110
b > = 110/10
b > = 11

so she can do 15 days of running plus 11 days of biking....which totals 26 days

The number of days that it would take for Kayla to accomplish her new goal is 26days.

Based on the information given in the question, the equation to solve the question will be:

6(15) + 10b > 200

Open the bracket.

90 + 10b > 200

Collect like terms

10b > 200 - 90

10b > 110

Divide both side by 10

10b/10 > 110/10

b > 11

Therefore, the total number of days required will be:

= 15 days + 11 days

= 26 days.

The number of days that it would take for Kayla to accomplish her new goal is 26days.
