Harry wants to go to a concert and buy a shirt from his favorite band. The tickets cost $190 and the shirt is $45. He has $50 so far saved up from chores. His mom will give him $15 every time he mows the lawn. Write an equation so show how many times will he need to mow the lawn in order to have enough money for the concert and a shirt.

Respuesta :

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
