Answer:
87.5%
Step-by-step explanation:
7 are shaded
8 total boxes are there
7/8= .875
.875*100=87.5%
-5 + 19 = 14
-5 - 19 = -24
14,-24
Mary's backpack: 25% of 65 = 0.25 * 65 = 16.25; 65 - 16.25 = $48.75
Roberto's backpack: 30% of 75 = 0.3 * 75 = 22.5; 75 - 22.5 = $52.5
Mary's backpack was a better buy because it was cheaper.
Two points can be (6,5) and (7,8)
