You and your four friends have $25 to spend on snacks. A medium size popcorn costs $2.50 and a medium soft drink costs $1.50. Write and graph an inequality that represents the numbers of medium boxes of popcorn and medium soft drinks you can buy.

Step-by-step explanation:

Step one:

given

Total money at hand=$25

cost of one popcorn=n $2.5

cost of drink= $1.5

total number of friends plus you= 4+1= 5

let the total amount spent be y

y= 5(2.5)+5(1.5)

y=12.5+7.5

y=20

The above shows that $20 is enough to cover the expenses, and there will be a balance of $5

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
