Answer: 20 lawns
Multiply each by 5 times for 20 yay woo hoo
That's really hard homework I really have never seen anything like that but I'll ask my sister.
Yes it does have interest on your card
Slope intercept form will help you find the function of the line :) [ y = mx + b ]
at time = 0 (y-intercept) the pool is 72in deep
the pool loses 2 inches of water every 1 hour. or -2/1
so your equation is y = -2x + 72
Good Luck!
