Blake needs 5 gallons of primer for the 5 rooms, and the primer is priced at $30.00 per gallon.
With a 20% discount, the price per gallon of primer is reduced by 20/100 * $30.00 = $6.00
So, the discounted price per gallon of primer is $30.00 - $6.00 = $24.00
The total cost of the primer for all 5 rooms is 5 gallons * $24.00 per gallon = $120.00
Blake also needs 5 gallons of paint for the 5 rooms, and the paint is priced at $25.00 per gallon.
The total cost of the paint for all 5 rooms is 5 gallons * $25.00 per gallon = $125.00
Therefore, the total cost of the primer and paint for all 5 rooms is $120.00 + $125.00 = $245.00
