The cash price of a laptop is $1299. It can be bought at hire purchase by making a deposit of $350 and 10 monthly payments at $120 each. (i) What is the TOTAL hire purchase

(ii) How much is saved by buying the laptop for cash

I) The TOTAL hire purchase of the laptop is; $1550

II) The amount saved by buying the laptop for cash is; $251

I) We are told that the laptop can be bought at hire purchase by making a deposit of $350 and 10 monthly payments at $120 each.

Thus;

Cost of laptop by hire purchase = 350 + 120(10)

>> 350 + 1200

>> $1550

II) Since the cash price is $1299, then amount saved = 1550 - 1299

>> $251

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
