Subtract $150 from $430 to get $280, the amount if money that Manuel has to earn to reach his goal.
If he is adding $35 to his account each month, then all you have to do is divide the amount you need by the amount you are earning each month to get the number of months until you reach your goal.
$280 divided by $35 is 8, so it would take 8 months for Manuel to reach his goal.
We call the ratio between two directly proportional quantities the constant of proportionality. When these two quantities may increase or decrease, the constant proportionality always remains the same
