Three friends share the total cost of a game. Joe pays 30%, mike pays 2/5 and tony pays the rest. Who paid the most ?

Mike pays the most.

Step-by-step explanation:

Joe pays 30%, given, and Mike pays 2/5, also given. You can covert 2/5. into a percentage by multiply both the numerator and denominator by 20 which gives you 40/100 = 40%. If Mike and Joe combined pay 40%+30% = 70%, then Tony only pays 30%. Therefore Mike would pay the most.

step-by-step explanation:

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
