30 letters in 1 day

Step-by-step explanation:

so 18 letters IS 60% OF the total letters ...

let x = total letters

" is " means = and " of " means multiply

turn ur percent to a decimal

so write ur equation like u read it ...

18 = 0.60x ... now divide both sides by 0.60

18 / 0.60 = x

30 = x <== = he types 30 letters in 1 day
