Since you took away 25% from the 100% value, we know 637.50 is 75% of the full value. So divide it by three to get the 25% value of 212.50, then multiply by 4 to get the full value of 850. So the original price was $850.

The original price is 478.13 (if you round it) because 637.50 times .25(its .25 because you need to turn it into a decimal) equals 159.375 then you subtract 637.50 by 159.375 and you get 478.125 then you round and get 478.13

Answer:

384 cm²

Step-by-step explanation:

The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.

To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:

For parallelogram:

Height (H) = 7.5 cm

Base (B) = 24 cm

Area of parallelogram (A₁) =?

A₁ = B × H

A₁ = 24 × 7.5

A₁ = 180 cm²

For rectangle:

Length (L) = 24 cm

Width (W) = 8.5 cm

Area of rectangle (A₂) =?

A₂ = L × W

A₂ = 24 × 8.5

A₂ = 204 cm²

Finally, we shall determine the area of the shape.

Area of parallelogram (A₁) = 180 cm²

Area of rectangle (A₂) = 204 cm²

Area of figure (A)

A = A₁ + A₂

A = 180 + 204

A = 384 cm²

Therefore, the area of the figure is 384 cm²

7) CJ was painting his apartment. In 15 minutes,
igomit [66]

y = 12x represents the gallons of paint used in x hours.

Step-by-step explanation:

CJ uses 3 gallons of paint in 15 minutes,

15 minutes = 3 gallons

1 minutes = \frac{3}{15} = \frac{1}{5} \ gallons\\

1 hour = 60 minutes

Gallons of paint used in 1 hour;

1 hour = \frac{1}{5}*60=12\ gallons

CJ uses 12 gallons of paint in 1 hour.

For x hours = 12*x = 12x

Gallons of paints used = y

y = 12x represents the gallons of paint used in x hours.
