Answer:
Largest AREA A = x × y = 250 × 500/3 = 125000 / 3 = 41666.67 ft²
Dimensions; X = 250 ft and Y = 500/3 ft
Step-by-step explanation:
Given the data in the question;
2x + 3y = 1000 -------- EQU 1
2x = 1000 - 3y
x = 500 - 3y/2
AREA = x × y = (500 - 3y/2)y
= 500y - 3/2y²
dA/dxy = 500 - 3y = 0
3y = 500
y = 500/3
so from equ 1
2x + 3(500/3) = 1000
2x = 1000 - 500
x = 250
So; Largest AREA A = x × y = 250 × 500/3 = 125000 / 3 = 41666.67 ft²
Dimensions; X = 250 ft and Y = 500/3 ft

Answer:
$70.
Step-by-step explanation:
Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:
(19 x 15) + X = 1615
285 + X = 1615
X = 1330
1330/19 = 70
Thus, the fixed amount Neda receives for each television is $70.
Answer:
(a). $20,000
(b). The estimate will be lower than the actual amount.
Step-by-step explanation:
We have been given that Michael saves $423 dollars a month for college.
(a). We know that 1 year equals 12 months.
4 years = 4*12 months = 48 months.
![\text{Actual amount saved}=\$423\times 48](https://tex.z-dn.net/?f=%5Ctext%7BActual%20amount%20saved%7D%3D%5C%24423%5Ctimes%2048)
Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:
![423\approx 400\\\\48\approx 50](https://tex.z-dn.net/?f=423%5Capprox%20400%5C%5C%5C%5C48%5Capprox%2050)
![\text{Actual amount saved}=\$400\times 50](https://tex.z-dn.net/?f=%5Ctext%7BActual%20amount%20saved%7D%3D%5C%24400%5Ctimes%2050)
![\text{Actual amount saved}=\$20,000](https://tex.z-dn.net/?f=%5Ctext%7BActual%20amount%20saved%7D%3D%5C%2420%2C000)
Therefore, Michael will save approximately $20,000 in 4 years.
(b).
The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.
Therefore, the estimate will be lower than the actual amount.
