The product of three and a number decreased by ten is thirteen

3x - 10 = 13 would be the verbal expression where x = a number

Hope this helps!

To decide which cake would be the best value for money, we will calculate the volume of each cake

Cake A: 9.5 × 13 × 2 = 247 inches³
Cake B: 12 × 14 × 1.5 = 252 inches³

The best value cake will be cake B

Cake B is 14 - 13 = 1 inch longer and 12 - 9.5 = 2.5 inches wider but it's also 0.5 inches shorter than cake A.
