I think the answer is 16 but I’m not entirely sure
52
Step-by-step explanation:
I don't really know what the other numbers are for but I'll just answer the first line.
Basically, you have to find what 10% of 130 is and multiply that number by 4.
130/10 = 13 (10% of 130)
4(13) = 52 (40% of 130)
You can verify this by typing in your calculator (130 x 0.40) and you should get 52.
You can also take 100% of 130 and substract by 60% of 130 to find 40%.
Answer:

Step-by-step explanation:
Answer:
70 standard boxes, 40 deluxe boxes
Step-by-step explanation:
standard: x
deluxe: y
x + y = 110
7x + 11y = 930
Multiply the first equation by 7 and subtract.
7x + 7y = 770
-(7x + 11y = 930)
You get -4y = -160
y = 40
Substitute y into the first equation.
x + 40 = 110
x = 70
Negative 3x over the power by four
