Worked solution

1(a)

1. Calculate the value of the numerical expression

1232335.01+2=9.516…\frac{\sqrt[3]{123^2}}{\dfrac{3}{5.01}+2}=9.516\ldots

To 3 significant figures,
9.516…≈9.529.516\ldots \approx 9.52

Answer

9.529.52

1(b)

1. Find the greatest price that would round to \$24 to the nearest dollar

A price that rounds to $24 to the nearest dollar satisfies

$23.50≤price<$24.50.\$23.50 \leq \text{price} < \$24.50.

Since money is stated to the nearest cent, the maximum possible price is

$24.49.\$24.49.

Answer

$24.49
