So therefore we first work out it takes 12 days so we cna condense this to 6x and make the equation -4x+6x = 12 to find how many press ups he used to do.
To find day increase = (x+5x) = 6x = 12
Or to find amount of press ups per day = 3x x 5x =30
Goals=30 the ratio is 6 units to 7 units goals=6 units goals=30 30=6 uints divide by 6 5=1 unit so miss=7 units 5 per unit times 7 units=35 answer is 35 miss
