Add 15 and 9, then subtract that by 87. 63 should be your answer.
We know that there are 21 buttons total. x is the number of small buttons and y is the number of large buttons.
Therefore, our first equation should be x+y = 21.
We know the small buttons sell for 3 dollars, meaning 3x represents how much is made from the small buttons. The larger buttons sell for 4 dollars, meaning 4y is how much is made from the large buttons.
We also know that the total of the buttons sold is 68 dollars. Therefore 3x + 4y = 68 is our second equation.
From this information, the answer is the first set.
To simplify you need to find the gcf Greatest common factor which is 3
3x67=201 and 3x10=30
now divide 30 divided by 3=10 and 201 divided by 3=67
so the answer is 10/67
Answer:
65 bikes
Step-by-step explanation:
The store buys the bikes that they sell for $35, and they sell them for $85, so in order to find the actual amount of money earned from one sale, you have to subtract how much they sell the bikes for by how much they bought them for, so:
85 - 35 = 50
Then, you divide the $3250 by the 50:
3250 / 50 = 65
So now we know that the store must sell 65 bikes a month to break even.
Need to know how much per person and how much per car..
to answer your question you will do it like this:
82×a(amount per person)=b
49×c (amount per car)=d
b+d= total amount for one trip
