The class is selling food at the school fair. pretzels cost $1.50, and bottles of water cost $1.00. the class sold a total of 107 items and collected $128.

Let's assume all the items were bottles of water.

107 * $1 = $107

The difference from the actual result is $21.

If we changed each bottle of water to a pretzel, that would increase by $0.5.

$21 / $0.5 = 42

Hence, the class sold 42 pretzels and (107 - 42) = 65 bottles of water.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
