You are mowing a lawn. after 12 minutes, 52% of the lawn still needs mowed. how long does it take to mow the entire lawn? write an equation that represents the percent y of the lawn that still needs mowed after x minutes.

y=

it takes minutes to mow the lawn

So this is a variation problem,

Area of the lawn mowed is directly proportional to the time of mowing

A = aT

48 = a12

Solve the proportionality constant

A = 4

So the equation is

Y = 4x

And time it takes 52% to mown

T = 52/4 = 13 min

Total 12 + 13 = 15 min

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
