H = 3000 - 40m (starts at 3000...decreasing at 40 ft per minute
h = 1200 + 50m (starts at 1200...rises 50 ft per minute
Number one is D
number 2 is A
(3x-2x) +2y +2
= 1x + 2y + 2
= x + 2y + 2
The difference in the cost per ounce is $0.05 per ounce
<h3>Fractions and proportion</h3>
Fractions are written as the ratio of two integers
If a 12-ounce jar of jam costs $2.40, the cost per ounce will be:
Unit cost = 2.40/12
Unit cost = $0.2
Similarly, if a 16-ounce jar costs $4.00, the price of a ounce will be:
Unit cost = 4/16
Unit cost. =$0.25
difference = $0.25 - $0.2
difference = $0.05
Hence the difference in the cost per ounce is $0.05 per ounce
