0. Juan has been saving for a new bike for two months. So far, he has saved
antiseptic1488 [7]

<u>Given</u>:

Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.

The money that he has saved so far is 30% of the cost of the bike.

We need to determine the total cost of the bike.

<u>Total cost of the bike:</u>

Let x denote the total cost of the bike.

The total cost of the bike is given by

30\% \ of \ x=150

The value of 30% can be written as \frac{30}{100}

Thus, we get;

\frac{30}{100} \times x=150

Multiplying both sides by \frac{100}{30}, we have;

x=150 \times \frac{100}{30}

Simplifying, we have;

x=\frac{15000}{30}

x=500

Thus, the value of x is 500.

Hence, the total cost of the bike is $500.

I've tried to get the answer for this 13 times now (not joking), plzzz help: write a formula that represents the number of peopl
gtnhenbr [62]

Answer:

  • 2820 seats
  • aₙ = 3n + 9

Step-by-step explanation:

<u>This is an AP with:</u>

  • The first term a₁ = 12
  • Common difference d = 3
  • Number of terms n = 40

<u>Number of the seats:</u>

  • Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
  • S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats

<u>Formula of nth term:</u>

  • aₙ = a₁ + (n - 1)d
  • aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
  • aₙ = 3n + 9
