The actual photo has an area of 16*20 inches, so 320 inches squared. The ratio between the digital and real photo is 16:20. On the other hand, the width to length of the digital photo is x:2.5. Cross multiply the two ratios and solve for x. 16/20*x/2.5 —> 20x = 40 —> x = 2. The width of the digital image is 2 inches, so multiplying the width times the length gives you a 5 inches squared area for the digital image. Answer: 5 in^2

Step-by-step explanation:
So to fund the answer, you need to find how much they can eat per minute: 32/5 = 6.4 (around 6 lunches)
Then you multiply this by 57: 57x6.4 = 364.8
We have
In order to obtain easily the table, we need to clear y
then we evaluate for values of x
if x=0
y=-4(0)+1=1
y=1
if x=1
y=-4(1)+1=-3
y=3
if x=2
y=-4(2)+1=-7
y=-7
if x=3
y=-4(3)+1=-11
y=-11
So the table for the given equation is
x y
0 1
1 -3
2 -7
3 -11
