Write a word problem for which you would use the equation 2/5x + 6 = 56

Isha is at an arcade. There is a base fee of $6 to enter the game room. Every game costs $0.4 or 40 cents to play. If Isha ends up spending $56 at the arcade, how many games did she play?

An explanation:

The base fee of $6 represents the constant 6 in the equation. Every game costs $0.4, which equals 2/5.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
