Answer:
Susan has suggested a correct method to calculate the amount of money
Step-by-step explanation:
Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.
Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.
John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.
Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.

The tin game's surface area 177 inch².
Step-by-step explanation:
Step 1:
To calculate the triangular prism's surface area, we calculate the areas of all the 5 sides.
We divide the prism into 2 triangles and 3 rectangles, find the area individually and then sum them all up in order to determine the entire triangular prism's area.
Step 2:
There are two triangles with base lengths of 10 inches and heights of 8.7 inches. To calculate a triangle's area we multiply with the product of the base length and it's height.
Area of 1 triangle = inch².
Area of both triangles = Area of 1 triangle × 2 = = 87 inch².
Step 3:
There are three rectangles with a common length of 10 inches and a width of 3 inches.
Any rectangle's area is given by multiplying the rectangle's length with its width.
Area of the 1 rectangle = inch².
Area of 3 rectangles = inch².
Step 4:
The area of the entire triangular prism = inch².
