The graph shows the savings of a
student over five months. How much did the student save in
total?
The horizontal axis on the graph
tells us the five months in which the student saved. These were January, February,
March, April, and May. The vertical axis tells us how many
pounds they saved each month. Each square on this vertical axis
represents four pounds. The amount of money that the
students saved in January is halfway between 16 and 20. This means that they saved 18 pound
in January.
In February, the amount saved is
halfway between 20 and 24. This is equal to 22 pounds. In the month of March, the student
saved halfway between eight and 12 pound. The midpoint of eight and 12 is
10. Therefore, the student saved 10
pound in March. In April, the student saved 16
pound. And finally, in May, the amount
saved was halfway between four and eight. This is equal to six pound.
Over the five months, the student
saved 18 pounds, 22 pounds, 10 pounds, 16 pounds, and six pounds. We can calculate the total amount
that they saved by adding 18, 22, 10, 16, and six. 18 plus 22 is equal to 40. 10 plus 16 is equal to 26. Adding six to this gives us 32. We need to add 40 and 32. This is equal to 72. Therefore, the student saved a
total of 72 pounds over the five months.
