The solution would be like
this for this specific problem:
Given:<span> x +y
= 390 </span>
2x + 4y = 1260
2x+4y=1260 ßdivide by 2
= x+2y=630
x+y=390 ßsubtract
= x+2y-x-y=630-390
y=240
x+240=390
x=390-240=150
<span>So, if they raised $1260 from the concession
stand, then they sold 240 sandwiches.</span>
Answer:
10
Step-by-step explanation:
The number of tiles in the design is 1 + 2 + 3 + ...
We can model this as an arithmetic series, where the first term is 1 and the common difference is 1. The sum of the first n terms of an arithmetic series is:
S = n/2 (2a₁ + d (n − 1))
Given that a₁ = 1 and d = 1:
S = n/2 (2(1) + n − 1)
S = n/2 (n + 1)
Since S ≤ 60:
n/2 (n + 1) ≤ 60
n (n + 1) ≤ 120
n must be an integer, so from trial and error:
n ≤ 10
Mr. Tong should use 10 tiles in the final row to use the most tiles possible.
