When x=8 and y=20. find y when x=68

170

Step-by-step explanation:

8/20=x/y

simplify. 2/5

2/5=68/y

68*5/2=y

68*5=340

340/2=170

y=170

$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)
