Asha bought 60 fruit baskets. 25% of the fruit baskets have 12 pieces of fruit in each basket. The remaining 75% of the baskets
iren2701 [21]

The complete model for the given question is;

Number of fruit baskets that contain 12 fruits = 15 baskets

Number of fruit baskets that contain 15 fruits = 45 baskets

We are told that he bought 60 fruit baskets.

Percentage of the fruit baskets that have 12 pieces of fruit = 25%

Percentage of the fruit baskets that have 15 pieces of fruit = 75%

Thus;

Number of fruit baskets that contain 12 pieces of fruit = 25% × 60 = 15 baskets

Number of fruit baskets that contain 15 pieces of fruit = 75% × 60 = 45 baskets

MARKING BRINLEST RIGHT NOWW HURRYY
natima [27]

Answer:

$275

Step-by-step explanation:

So she put $60 into savings....

X is the amount of her paycheck...

after buying the clothes she had X-75

She spend (2/5)(x-75)  on books

The amount deposited into saving and spent on groceries totals 120.

So

X = 75 + (2/5)(x-75) + 120

X = (2/5)(X-75) + 195

X = (2/5)X - 30 + 195

X = (2/5)X + 165

(3/5)X = 165

X = 165*5/3 = 5*55 = 275

Starts with 275

spent 75 on clothes, which makes it 200.

2/5 of 200 is 80, which makes it 120.

60 deposited into savings and 60 on groceries

Her paycheck was 275
