Name: Dana Dutch
1. Find the unit price for the item: $4.44 for a dozen bananas.
If 12 bananas = $4.44
Then 1 bana = X
X= 1 times $4.44 dived by 12
X=0.37 per banana
Because 0.37 times 12 =4.44
2. A basketball player scored a total of 115 points in the first five games of the season. If
he continues at the same pace, how many points should he score in the 20game season?
115 * 20 / 5
= 115 * 4
= 460 points
3.
Solve for the unknown:
cross multiply to get:
m * 52 = 8 * 39
52m = 312
then divide both sides of the equation by 52 to get the value of m:
m = 312/52
m= 6
