Vina has $4.70 in quarters, dimes and nickels in her purse. She has eight more dimes than quarters and six more nickels than qua
DanielleElmas [232]

Nickels (0.05): Q + 6

Dimes (0.10): Q + 8

Quarters (0.25): Q

Nickels        +    Dimes      +  Quarters  = Total

0.05(Q + 6)  + 0.10(Q + 8) +   0.25(Q)    = 4.70

0.05Q + 0.30 + 0.10Q + 0.80 + 0.25Q = 4.70

                                         0.40Q + 1.10 = 4.70

                                                   0.40Q = 3.60

                                                            Q = 9

Nickels (0.05): Q + 6  = (9) + 6  = 15

Dimes (0.10): Q + 8   = (9) + 8   = 17

Answer: Nickels = 15, Dimes = 17, Quarters = 9

The talent show consists of introduction and talent performance. It could be written into this equation
Talent show duration= introduction + talent performance

Each performer for the talent show has 6 minutes for their show, the <span>introduction of the talent show is 24 minutes, and the total duration should be 150 minutes. Then, maximum performance count of the show would be:
</span>
Talent show duration= introduction + talent performance
<span>150 min = 24 min + (performance count * 6min)
</span>performance count = (150min - 24min) / 6 min
performance count=21
