A boy spends 3/8 of his journey in playing games on his mobile. Then 4/5 of the remaining time talking to his sister. If he has 5 min to complete his journey, what is the total time of the journey

40 mins

Step-by-step explanation:

time spent talking to his sister = (1 - 3/8) x 4/5 =

5/8 x 4/5 = 1/2

total fraction of time spent playing games and talking to his sister :

=

fraction of time remaining to complete the journey = 1 - 7/8 = 1/8

let t = total journey time

1/8 x t = 5

multiply both sides of the equation by 8

t = 5 x 8 = 40 minutes

$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)
