fomenos

Answer:

$59.96

Step-by-step explanation:

Given:

The science club has raised $154. 24 to buy food for a polar bear cub at the zoo.

It costs $53.55 to feed the cub each week.

Question asked:

How much more money does the club need to raise to feed the cub for one month (four weeks)?

Solution:

Cost of feed for the cub for 1 week = $53.55

Cost of feed for the cub for 4 weeks = $53.55 \times 4 = $214.20

Money raised by the science club = $154. 24

More money needed by science club = Cost of feed for 4 weeks - Money raised by the science club

More money needed by science club = $214.20 - $154. 24

                                                               = $59.96

Thus, the science club will be needed $59.96 more money  for one month (four weeks) feed.

Tomtit [17]

127 children and 264 adults swam at the public pool that day

Step-by-step explanation:

On a certain hot​ summer's day

  • 391 people used the public swimming pool
  • The daily prices are $1.25 for children and $2.25 for adults
  • The receipts for admission totaled $752.75

We need to find how many children and how many adults swam at the public pool that​ day

Assume that the number of children is x and the number of adult is y in that day

∵ x children swam that day

∵ y adults swam that day

∵ 391 people used the swimming pool that day

- Add x and y, then equate the sum by 391

∴ x + y = 391 ⇒ (1)

∵ The daily price for children is $1.25 per child

∵ The daily price for an adult is $2.25

∵ The receipts for admission totaled $752.75

- Multiply x by 1.25 and y by 2.25, then add the products and

  equate the sum by 752.75

∴ 1.25x + 2.25y = 752.75

- Divide each term by 1.25 to simplify the equation

∴ x + 1.8y = 602.2 ⇒ (2)

Now we have a system of equations to solve it

Subtract equation (1) from equation (2) to eliminate x

∵ (x - x) + (1.8y - y) = 602.2 - 391

∴ 0.8y = 211.2

- Divide both sides by 0.8

∴ y = 264

- Substitute the value of y in equation (1) to find x

∵ x + 264 = 391

- Subtract 264 from both sides

∴ x = 127

127 children and 264 adults swam at the public pool that day
