Answer:
v=pi252(14)
Step-by-step explanation:
Answer:
10 quarters = $2.50
10 nickels = $0.50
that leaves $0.20 for other coins (dimes / pennies)
Step-by-step explanation:
First, suppose she has only quarters and nickels and no other coins. Then if C is the identical number of coins of each type, then 5C + 25C = 320, so 30C = 320 and 3C = 32, but there is no integer solution to this. So she must have at least one other type of coin.
Assume she has only quarters, nickels, and dimes. Then if D is the number of dimes, 5C + 25C + 10D = 320, which means 30C + 10D = 320, or 3C + D = 32. The smallest D can be is 2, leaving 3C = 30 and thus C = 10. So in this scenario she would have 10 quarters, 10 nickels, and two dimes to make $2.50 + $0.50 + $0.20 = $3.20.
This has to be the highest number, because if she had 11 quarters and 11 nickels, that alone would add up to 11(0.25) + 11(0.05) = $3.30, which would already be too much.
Answer:
300
Step-by-step explanation:
Day 1: $70
Day 2: $80
Total commission = day 1 × 2 + day 2 × 2
= 70 × 2 + 80×2
= 140 + 160
= 300
Or
Total commission = 2(day 1 + days 2)
= 2(70 + 80)
= 2(150)
x = 300
I think it is d not sure tho
False I think it is if I’m right
