Answer:

Approximately 13 times

Step-by-step explanation:

given data

amount at hand=$50

total cost for the ticket and shirt= 190+45=$235

amount earned per time he lawns= $15

let the number of time he lawns be x

and let the total amount be y

the expression for the situation is

y=mx+c

235=15x+50

solve for x

235-50=15x

185=15x

divide both side by 15

x=185/15

x=12.3

12.3 time

or 13 times
