Small bag: A 175 g bag costs 55p.
Medium bag: A 525 g bag costs £1.76.
Large bag: A 1.15 kg bag costs £3.51.

Find the cost per gram for each bag of sugar.
Round your answers to 3dp.

Answers

Answer:

The cost per gram for each bag is:

Small bag: 0.00314 £

Medium bag: 0.00335 £

Large bag: 0.00305 £

Step-by-step explanation:

Small bag:

If 175 g cost 0.55 £, 1 g will be:

Medium bag:

If 525 g cost £ 1.76, 1g will be:

[tex] \frac{1g*1.76 \£}{525\: g} = 0.00335 \£[/tex]

Large bag:

If 1150 g cost £ 3.51, 1g will be:

[tex] \frac{1g*3.51 \£}{1150\: g} = 0.00305 \£[/tex]

Answer:

the slope is 2

Step-by-step explanation:

to find slope all you need to do is look at the places where the line and the graph intersect. you should be able to find atleast 2 places. Once you have done that, count up how ever many spaces it is until you are on the same line with the place where the line intersects with the graph remember that number in your head, then could left or right until you are on top of the other place where it intersects, remember that number. In this case I counted 2 spaces up and 1 space to the left which gave me 2/1 which is 2

The sprayer's base price is $820,000, and it would cost another $17,500 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $604,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $15,500.
