Martin decided to buy 2 bags of grapes weighing 5 and two-thirds pounds each, instead of the 3 bags weighing 4 and one-fifth pou
Juli2301 [7.4K]

Answer: He ended up with about 1 pound less grapes

Step-by-step explanation:

2 bags of grapes weighing 5 and two-thirds pounds each will give a total weight of:

= 2 × 5 2/3

= 2 × 17/3

= 34/3

= 11 1/3 pounds

3 bags weighing 4 and one-fifth pounds each, will give a weight of:

= 3 × 4 1/5

= 3 × 21/5

= 63/5

= 12 3/5

He ended up buying lesser grapes. This was about 12 3/5 - 11 1/3 = 1 4/15 less. This means that he ended up with about 1 pound less grapes

Lets look at the info we have:-

23 orders for Pepsi.
15 orders for mountain dew.

How many more orders have there been for Pepsi than for Mountain Dew?

To answer this we will subtract the amount of Pepsi's ordered by the amount of Mountain Dew's ordered. The answer will be the amount of more Pepsi's ordered than the Mountain Dew's.

We were RIGHT!!!

So, 8 more Pepsi's were ordered than Mountain Dew's.

The number of hours, t, it takes a boat to travel 15 miles upstream is represented
iogann1982 [59]

The equation of c is an illustration of subject of formula

The equation of c in terms of r and t is c = r - 15/t

<h3>How to determine the equation?</h3>

The equation is given as:

t = 15/(r - c)

Cross multiply

t(r - c) = 15

Divide both sides by t

r - c = 15/t

Subtract r from both sides

-c = -r + 15/t

Multiply both sides by -1

c = r - 15/t

Take LCM

c = \frac{rt - 15}{t}

Hence, the equation of c in terms of r and t is c = \frac{rt - 15}{t}
