Mario sold concessions during the hockey tournament at the high school. he sold bottled water for $2.50 each and hamburgers for $5.50 each. by the end of the tournament, mario’s sold 350 items for a total of $1,325. which statements about the concession sales are true? check all that apply.

suppose he sold w numbers of bottled water and h numbers of hamburger.

mario's sold 350 items which means sum of w and h must be equal to 350. so,

w+h=350.

each bottled water cost $2.50. so, w bottled water cost 2.50w.

similarly each hamburgers cost $5.50. so, h hamburgers cost 5.50h.

mario sold total of 1,325. so, sum of 2.50w and 5.50h must be equal to 1,325.hence,

2.50w+5.50h=1325.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
