Which model represents 1/3

2nd one because 2/6=1/3

Step-by-step explanation:

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
