Carolyn has $2.55 in her purse in nickels and dimes. The number of nickels is nine less than three times the number of dimes. Fi
Flauer [41]

Hi, the answer is ;

Answer:

12 dimes and 27 nickels

Step-by-step explanation:

.05N + .1d = 2.55

N= 3d - 9

0.05 (3d-9) + 0.1d = 2.55

0.15d - 0.45 + 0.1d = 2.55

0.25d = 2.55 + 0.45

0.25d = 3

D = 12

N = 3 (12) - 9

N = 36 - 9

N = 27

garri49 [273]

If Mia sold 2 more hats on each suceeding day, after working 40 days it is expected Mia had sold a total of 1523 hats.

<h3>How many hats will Mia sell everyday?</h3>

Day: Hats

  • 2=3
  • 3 = 5
  • 4=7
  • 5= 9
  • 6=11
  • 7= 13
  • 8= 15
  • 9=17
  • 10=19
  • 11= 21
  • 12=23
  • 13= 25
  • among others

You can notice the number of hats she will sell follow a pattern as there are only sequential odd numbers.

<h3>How many hats will Mia sell in total?</h3>

By following the sequence let's add the hats she will sell everyday:

  • 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25 + 27 + 29 + 31 + 33 + 35 + 37 + 39 + 41 + 43 + 45 + 47 + 49 + 51 + 53 + 55 + 57 + 59 + 61 + 63 + 65 + 67 + 69 + 71 + 73 + 75 + 79 = 1523
