You are a dress maker and buy many of your fabrics overseas. You have been given a new design for a dress that each dress takes 1.5 metres of fabric that you need to buy from a supplier. You are making 12 dresses. The fabric is sold for $22.50 per
yard. How many yards would you need to order and what would it cost you?

Total yards = 19.685 yards

Total cost = $442.9125

Step-by-step explanation:

Fabrics per dress = 1.5 meters

Number of dresses = 12

Total fabrics needed = 1.5 meters × 12

= 18 meters

Convert 18 meters of fabrics into yards

18 meters = 19.685 yards

Cost of fabric per yard = $22.50

Total cost of fabrics in yards = 19.685 yards × $22.50

= $442.9125

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
