Answer:
1 = t/45 + t/105
Step-by-step explanation:
Greg's father mow a lawn in 45 minutes that means that he mow in a rate of 1/45
Greg mow a lawn in 1 hour 45 minutes (105 minutes) that means that he mow in a rate of 1/105
If they mow a lawn in t minutes that means the rate is 1/t
Then, the rate in which they mow a lawn has to be equal to the sum of the rate individually as follows
1/t = 1/45 + 1/105
1 = t/45 + t/105
Percent means parts out of 100
7%=7/100=0.07
'of' means multiply so
7%=0.7
7% of 280=0.07 times 280=196
12%=0.12
12% of 300=36
2%=0.02
2% of $1250=$25
