ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions

Answer:

last option

Step-by-step explanation:

It will take 200 / 5 = 40 months for Sara's phone to lose all its value, therefore, the domain is 0 ≤ t ≤ 40 because you can't have negative months. Since negative money is not a thing, the range has to be 0 ≤ V(t) ≤ 200 because it stops at 0 and starts at 200.

Becky invests £5000 for 2 years in a bank account.

Arte-miy333 [17]

Answer:

£300

Step-by-step explanation:

We apply the formula for Simple Interest:

$I = \frac{P * R * T}{100}$

where P = Principal

R = Rate of interest

T = Time elapsed (in years)

We are given that P = £5000, R = 3%, T = 2 years

The interest after 2 years will be:

$I = \frac{5000 * 3 * 2}{100} \\\\\\I = \frac{30000}{100}$

I = £300

The interest Becky will get after 2 years will be £300.

On a certain hot summer's day, 659 people used the public swimming pool. The daily prices are $ 1.75 for children and $ 2.00 fo

valentinak56 [21]

351 children and 308 adults swam at the public pool.

Step-by-step explanation:

Let,

Children = x

Adults = y

Price per children = $1.75

Price per adult = $2.00

According to given statement;

x+y=659 Eqn 1

1.75x+2y=1230.25 Eqn 2

$Multiplying\ Eqn\ 1\ by\ 2\\2(x+y=659)\\2x+2y=1318 \ \ \ Eqn\ 3\\Subtracting\ Eqn\ 2\ from\ Eqn\ 3\\(2x+2y)-(1.75x+2y)=1318-1230.25\\2x+2y-1.75x-2y=87.75\\0.25x=87.75\\Dividing\ both\ sides\ by\ 0.25\\\frac{0.25x}{0.25}=\frac{87.75}{0.25}\\x=351\\Putting\ value\ of\ x\ in\ Eqn\ 1\\351+y=659\\Subtracting\ 351\ from\ both\ sides\\351-351+y=659-351\\y=308$

351 children and 308 adults swam at the public pool.
