Answer:
1/20
Step-by-step explanation:
The area of a rectangle is found by Area = length x width so here the width is 2/5 and the length is 1/8 so... (2/5) x (1/8) = 1/20 square meters
6-by=19
minus 6 from both sides
-by=19-6
-by=13
divide both sides by -b
y=13/-b
y=-13/b
You would do for pens
22 x 1.15 =25.30
And for markets
15 x 2.05 = 30.75
And since you are trying to find how much he spent in all you would add the two sums
25.30 + 30.75 = 56.05
