Rate is a ratio of different units ( a quantity times a quantity), such as miles per hour.
Unit rate is a rate with a denominator of 1.
To find unit rate, divide the total cost by the quantity:
0.89 / 16 = 0.0556 per ounce.
(1/2) * x^3 + 3.4y when X = 2 and Y = 5.
= (1/2) * (2^3) * 3.4(5)
= (1/2) * 8 * 17
= (1/2) * 136
= 136/2
= 68.
