blank square in 1st column for total hours (x) = 25
last blank square in 2nd column for total earnings (y) =297
last square for equation enter [ 9 ]
( total earnings per week (y) = 9 × total number of hours (x)
Total earnings per week (y) = 9 × total number of hours (x)
A mathematical statement that is made up of two expressions connected by an equal sign.
Given data :
Total hours(x) Total Earnings(y)
20 180
25 225
27 243
30 270
By comparing the the first data, we can say that:
Total hours = 9 times the total earnings
So, for earnings 225
Total hours= 225/9= 25
Also, for earnings 243
Total hours= 243/9= 27
Last, for earnings 270
Total hours= 270/9= 30
And, total earnings per week (y) = 9 × total number of hours (x)
