Marc mows lawns for $25 each lawn, plus $5 for every hour he spends mowing. The equation for his total earnings per lawn is y = 25 + 5h, where y represents his total earnings and h represents the number of hours he works.
The equation for Marc's total earnings per lawn is y = 25 + 5h.
The equation y = 25 + 5h represents Marc's total earnings for mowing a lawn.
The $25 is the fixed amount he earns for mowing a lawn, while the $5 represents his additional earnings for each hour he spends mowing.
To find his total earnings for a certain number of hours, you can substitute the value of h (hours) into the equation.
For example, if Marc mows a lawn for 3 hours, you would substitute h = 3 into the equation:
y = 25 + 5(3)
y = 25 + 15
y = 40
So, when Marc mows a lawn for 3 hours, his total earnings would be $40.
