An ice skating arena charges an admission fee for each child plus a rental fee for each pair of ice skates. John paid the admission fees for his six nephews and rented 5 pairs of ice skates. He was charged $32.00. Juanita paid
the admission fees for her seven grandchildren and rented five pairs of ice skates. She was charged $35.25. If a
represents the amount of the admission fee and represents the skate rental fee, which of the following
systems of equations can be used to represent this situation.
A. 32.00a +5r = 5
35.25a +5r = 7
B. 5a + 6r = 32.00
5a + 7r = 35.00
C. 6a +5r = 32.00
7a +5r = 35.25
D. 8a +5r = 32.00
7a+ 7 = 35.00

there is nothing below so i cannot

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

there are no choices to this, can you give us some choices so that i can answer it
