The required, Frances uses 220 small cups to serve punch.
The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Frances used small, medium, and large cups to serve punch.
Let number of small and large cups be x and y,
According to the question,
She used 79 more medium cups than a large cups.
y = 243 - 79
y = 164
She used 56 more small cups than large cups.
x = 164 + 56
x = 220
Thus, the required, Frances uses 220 small cups to serve punch.

A: 6.4 cm
B: 5.0 cm
C:5.5 cm
D: 4.4 cm
The actual wingspan of fly is 5.5cm
Step-by-step explanation:
Given,
Scale of drawing;
4mm = 1cm
Ratio of mm to cm = 4:1
Wingspan of fly in drawing = 22mm
Let,
x be the actual wingspan.
Ratio of mm to cm = 22:x
Using proportion;
Ratio of mm to cm :: Ratio of mm to cm
Product of extreme = Product of mean
Dividing both sides by 4
The actual wingspan of fly is 5.5cm
