Answer:
445p + 140 ; 7 loaves of bread
Step-by-step explanation:
To make each p loaf, you need 445 grams of flour. This means that if you have 2p, you will need 2 x 445 grams of flour. So, whatever value p is, you will need to multiply that amount by 445 to find the total grams of flour needed.
<em>Additionally</em>, you need 140 grams for sprinkling. This is a consistent amount, no matter what your p-value is.
(theoretically, 0 as p should make you need 0 grams of flour but I don't think this is where the problem was going)
So, you will need p [number of loaves] x 445 grams, plus 140 grams for sprinkling
This is expressed as:
445p + 140
(option d)
If you have 3400 grams of flour, you will still need to remove 140 grams of that amount to sprinkle. So, the total amount of flour left for your loaves is 3,260 grams (3400 - 140 = 3260)
Then, you will need 445 grams of flour for each loaf. So, you will have to divide the total flour by 445 to find how many loaves you can make. (3260 / 445 = 7.326 [rounded] )
You can't make 0.32 loaves of bread, so you can only make the 7 loaves of bread (and then have extra.)
So, if you have 3400 grams of flour, you could make 7 loaves of bread.
