Lorenzo bought 3 trampolines and 1 basketball goal for the boy\'s camp. He paid a total of $1,189 for all four items. If the trampolines cost $384 each, how much did he pay for the basketball goal?

Solution

1) Cost of each bed = 419 and cost of table = 327.

Therefore, cost of 3 beds + 1 table = 3*419+327 = $1584

2) 5 dozen donuts = 5*12 = 60 donuts

If each tray had x number of donuts then 3 trays have 3x donuts. 3x=50 gives x=12

So each tray had 12 donuts

3) 1960 is the total number of seats. Let x be the number of seats in a section. So 8 sections have 8x seats.

8x=1960 gives x=245

3 sections will haave 3x = 3*245 = 735 seats

4) Trampoline costs 348. Let cost of a basketball goal be x.

Then 3 trampolines and 1 baskbetball goal cost 3*348+x=1044+x

Total was 1189 so 1044+x=1189

Hence x=1189-1044=145

Cost of each basketball goal is 145.
