At an icecream parlor, ice cream cones cost $1.10 and sundaes cost $2.35. One day, the receipts for a total of 172 cones and sundaes were $294.20. How many cones and sundaes were sold?

Answers

2.35 + 1.10 = 3.45
2.35 / 3.45
1.10 / 3.45

294.20 / 3.45 x 1.10 = 93.80 to 4sf
294.20 / 3.45 x 2.35 = 200.40 to 4sf

93.80 + 200.40 = 294.20

93.80 / 1.10 = 85.2727272727
200.40 / 2.35 = 85.2765957447

85 + 85 = 170      need two more

84 x 1.10 = 92.40    84 x 2.35 = 197.4
88 x 2.35 = 206.8    88 x 1.10 = 96.8
                = 299.2                    = 294.20

Answer: 84 sundaes and 88 ice cream cones were sold.

Simplify completely the quantity x squared plus x minus 12 over quantity x squared minus x minus 20 divided by the quantity 3 x squared minus 24 x plus 45 over quantity 12 x squared minus 48 x minus 60.

Answers

x² + x - 12 / x² - x - 20  ÷ 3x² - 24x + 45 / 12x² - 48x - 60

x² + x - 12 / x² - x - 20 * 12x² - 48x - 60 / 3x² - 24x + 45

(x² + x - 12)(12x² - 48x - 60)
(x² - x - 20)(3x² - 24x + 45)

12x^4 - 48x³ - 60x² + 12x³ - 48x² - 60x - 144x² + 576x + 720
3x^4 - 24x³ + 45x² - 3x³ + 24x² - 45x - 60x² + 480x - 900

12x^4 - 48x³ + 12x³ - 60x² - 48x² - 144x² - 60x + 576x + 720

3x^4 - 24x³ - 3x³ + 45x² + 24x² - 60x² - 45x + 480x - 900

12x^4 - 36x³ - 252x² + 516x + 720

A worker has a gross wage of $560 per week and deductions of ; $180 loan repayments, $145.60 tax,

Answers

Gross wage = 560
loan repayments = 180
tax = 145.60

Net gross wage = 560 - [ 180+145.60 ]
                          = 560 - 325.6
                          = 234.4
