Adelivery truck is transporting boxes of two sizes: large and small. the large boxes weigh 50 pounds each, and the small boxes weigh 30 pounds each. there are 120 boxes in all. if the truck is carrying a total of 4900 pounds in boxes, how many of each type of box is it carrying? a delivery truck is transporting boxes of two sizes: large and small. the large boxes weigh 50 pounds each, and the small boxes weigh 30 pounds each. there are 120 boxes in all. if the truck is carrying a total of 4900 pounds in boxes, how many of each type of box is it carrying?

55 small boxes, 65 large boxes.

Step-by-step explanation:

First, we let x = the amount of big boxes and let y = the amount small boxes. Then, we know that any combination of such will equal 120 so we say

x + y = 120

We also know that we have to fill 4900 pounds, so we can say

50x + 30y = 4900

Then, we can use either substitution or elimination. I'll do substitution. we make the first equation

x = 120 - y

And now we can plug this into our second equation

50(120 - y) + 30y = 4900

Then we distrubute

6000 - 50y + 30y = 4900

Then simplify

6000 - 20y = 4900

Subtract 6000 from both sides

-20y = -1100

then divide both sides by -20

y = 55

so there are 55 small boxes, which means we can subtract 55 from 120 to get 65 large boxes.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
