Answer:
25/8
Step-by-step explanation:
Given That:
R = 8x+4y
X= 8
R = 30.
So, 8 x 8 +4y = 30
Simplify, Rearrange and solve.
64 + 4y = 30
4y = 30/64 = 15/32
y = 15/32 divided by 4
y = 15 / 32 x 1/4
y = 15/(32 x 4) = 15/128

3³ - (4² - 2³)
3³ = 3x3x3 = 27
4² = 4x4 = 16
2³ = 2x2x2 = 8
3³ - (4² - 2³) = 27 - (16 - 8) = 27 - 16 + 8 = 19 (answer C)

Answer:
Each monthly payment is $ 49.05, and in total Tom paid $ 648.60.
Step-by-step explanation:
Given that Tom buys a DVD player on 12 monthly payments, whose cash price is $ 600, and he pays a 10% deposit and the store charges 9% interest, to determine how much is each payment and the total amount Tom pays for the DVD player the following calculations must be performed:
600 - 600 x 0.1 = 540
540 x 1.09 = 588.6
588.6 / 12 = 49.05
Thus, each monthly payment is $ 49.05, and in total Tom paid $ 648.60.
