I'm going to assume that the question was $1.99 × 10 because $1.99 $1.99; × 10 is not possible, so if that was the question, the answer would simply be false. The answer I got for $1.99 × 10 was 19.9

19.9

$(10.3(2.5)+3.1(2))\div 110$

Step-by-step explanation:

A_1 = Area of 1st rectangle = $(10.3\times 2.5)\ \text{ft}^2$

A_2 = Area of 2nd rectangle = $(3.1\times 2)\ \text{ft}^2$

$1\ \text{pound of grout}=110\ \text{ft}^2$

$\Rightarrow 1\ \text{ft}^2=\dfrac{1}{110}\ \text{pound of grout}$

The number of pounds required for the counter top is

$\text{Total area}\times \text{The amount of grout used in 1 ft}^2$

$=A_1+A_2\times \dfrac{1}{110}=(10.3(2.5)+3.1(2))\times \dfrac{1}{110}\\ =(10.3(2.5)+3.1(2))\div 110$

The required expression is $(10.3(2.5)+3.1(2))\div 110$ .
