Answer:
10% discount
Step-by-step explanation:
If you take 369 divided by 410 it gives you 0.9 which is equal to 90% which then leads us to realized that if 369 is 90% of 410 then the discount would have to be 10%
For Question 3,
15 ?
__ = ____
120 100
120?=1500
1500/120=12.5
?=12.5%
Question 4
I think it is $462.80
12 ft * 10 ft = 120 sq ft
½ * 6 ft * 7 ft = 21 sq ft
120 sq ft - 21 sq ft = 99 sq ft (it is area of the composite shape)
2(5k+1)
2x5x2+1 =21
K=2 | 21
2x5x3+1 =31
K=3 | 31
