Answer:
1. Shade 7 boxes in.
If 100% is 400 each 10% segment would be 40 and in order to get 70% (or 280) we shade in 7 boxes.
2. The football team scored 280 points. We get this number by multiplying .70 by 400
3. Marcy would spend more money.
To do this problem we multiply the percent by how much they have to get how much they spend.
Stephenson: 12% of 200$
.12 x 200 = 24$
Marcy: 8% of 350$
.08 x 350 = 28$
