Answer:
500 miles
Step-by-step explanation:
To find out how many miles Candice can hike at max, use the equation 11 + 0.14x = 81.
11 + 0.14x = 81
Subtract 11 from both sides. This undoes the +11.
0.14x = 81 - 11
Subtract 11 from 81 to get 70.
0.14x = 70
Divide both sides by 0.14. This undoes the multiplication by 0.14.
x = 70/0.14
I recommend converting 0.14 into a fraction. That would be 7/50.
x = 70/(7/50)
Find the reciprocal of 7/50 (50/7). Switch the sign from division to multiplication.
x = (70 * 50)/7
Multiply 70 by 50 to get 3500.
x = 3500/7
Divide 3500 by 7 to get 500.
x = 500
At max, Candice can hike 500 miles.
