Question

Can someone help me out with this inequality problem?? Will give brainliest to best answer!!

Answer 1

Answer:

250x + 525y ≤ 7800

no, 15 refrigerators and 8 pianos will not fit on the truck

Step-by-step explanation:

we know that x is the refrigerators and each one is 250 lbs

this can be written as 250x

we know that y is the pianos and each one is 525 lbs

this can be written as 525y

we also know that "no more than" is the same that as less than equal to

so this can be written as ≤

we can also say that the refrigerators and pianos has to be ≤ 7800

so now we have: 250x + 525y ≤ 7800

plug in 15 to x and 8 to y

250(15) + 525(8) ≤ 7800

3750 + 4200 ≤ 7800

7950 ≤ 7800

this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck
