Part A:

  • What We Need to Find is How Much money He Made over the summer

Setting Up the Problem We Would Do 160 + 180   Because we are trying to figure how Much money he made over the summer.

160 + 180 = 340

So Javonie Made 340$ over the Summer

Each key on the student calculators is 15 millimeters wide, and each key on the demonstration calculator is 4.5 centimeters wide
sammy [17]

Answer:

The answer to your question is 75 cm

Step-by-step explanation:

Data

Student calculator                Demonstration calculator

width = 15 mm                       width = 4.5 cm

height = 250 mm                   height = ?

Process

1.- Convert the width of the demonstration calculator to mm

                  10 mm ---------------- 1 cm

                   x        ---------------- 4.5 cm

                  x = (4.5 x 10) / 1

                  x = 45 mm

2.- Use proportions to find the height of the demonstration calculator

                  250 / 15 = x / 45

- Solve for x

                  x = (250 x 45) / 15

-Simplification

                  x = 11250 / 15

-Result

                 x = 750 mm

3.- Conclusion

The height of the demonstration calculator is 750 mm or 75 cm
