Answer:
$3.98(estimated)
Step-by-step explanation:
3c (cake) + 2(2c - 11) (bread) = 5.87
3c + 4c - 22 = 5.87
7c - 22 = 5.87
7c = 5.87 + 22
7c = 27.87
c = 3.98

Answer:
See below
Step-by-step explanation:
The values in the table change by $3.80 from one line to the next. Since each change from line to line changes in number of photos by 20, the average cost per photo is $3.80/20 = $0.19. There is apparently a $5.80 -3.80 = $2.00 shipping charge for numbers of photos in the range shown in the table.
Thus, the piecewise function has 3 pieces:
for x < 100: $2.00 + 0.19x
for x < 200: $4.50 + 0.17x
for x ≥ 200: $0.15x
This could be written as ...

If I’m correct this is supposed to be a decimal ( here we use the dot not the comma ) but if so then 32.52 a good way to remember is 5 or more let it sore (meaning round up) four or less let it rest (meaning it stays the same)
