The 1st row has 15 chairs.
The 2nd row has 15 + 3 = 18 chairs.
The 3rd row has 18 + 3 = 15 + 2•3 = 21 chairs.
The 4th row has 21 + 3 = 15 + 3•3 = 24 chairs.
The pattern continues, so that the n-th row has 15 + (n - 1)•3 = 3n + 12 chairs.
If there are 15 rows, then the total number of chairs is
where we use the formulas
Mr Reams uses 10 cups of paint to fill the small dishes, therefore, the amount of paints left in the bowl is 2 cups.
<h3>How to convert ounces to cups?</h3>
He mixes 12 cups of paints in a large bowl.
He uses the paint to fill 40 small dishes with 2 fluid ounces of paint each.
1 small dish = 2 fluid ounces
40 small dishes = 80 fluid ounces
Therefore,
1 fluid 0unces = 0.125 cups
80 fluid ounces = ?
cross multiply
amount of paint filled = 80 × 0.125 = 10 cups
Therefore, the amount of cups pf paint Mr Reams have left in the bowl is 12 cups - 10 cups = 2 cups.
