Answer:
0.8
Step-by-step explanation:
9(0.5y+0.4)=590.1y+1.3)+0.3
4.5y+3.6=0.5y+6.5+0.3
4.5y+3.6=0.5y+6.8
4.5y-0.5y=6.8-3.6
4y=3.2
y=0.8
Answer: the regular price is $6.5 each.
Step-by-step explanation:
Let x represent the regular price of a ticket to a basketball tournament.
Discount tickets to a basketball tournament sell for $4.00 each. Sam spent $60.00 on discount tickets. This means that the number of tickets that Sam bought is
60/4 = 15 tickets
The cost of 15 tickets at the regular price is 15x
Since the amount he paid is $37.5 lesser than what he would have paid if he bought the tickets at the regular price, then
15x = 60 + 37.5 = 97.5
x = 97.5/15
x = 6.5
Answer:
a
Step-by-step explanation:
To answer this item, we are first to determine the common factor between the amounts of the cement, sand, and gravel.
If we let x be this factor, the amount of the cement would be x. Similarly, the amount of sand is 3x, and lastly the amount of gravel is 4x. Then, we establish the equation that would let us relate the amounts.
x + 3x + 4x = 480
Simplifying,
8x = 480
x = 60
Hence, the amount of cement is 60 kg, that of sand is 180 kg. Lastly, the amount of gravel is 240 kg.
