La temperatura ambiente es 28° C, después de un minuto el termómetro marca 37° C y después de un minuto y medio el termómetro marca 40° C. ¿Cuál es la

temperatura inicial?

$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)
