Answer:
$91.75
Step-by-step explanation:
babysitting = B
Farmers Market = F
9.5B + 12.25F = Total money earned
9.5 (4.5) + 12.25 (4) = $91.75
15- 16 yd
16- 12 cm
17- 49 mi
18- 14 ft
Shorter side: 130ft
longer side: 260ft
greatest possible area: 33800ft^2
basically get the equations for area and perimeter which will be
A: lw (length x width)
P: l + 2w
Substitute them into eachother and you get the equation:
-2w^2+520w = A
find the vertex of this parabola which will give you the greatest width which is 130m
Then u can find length and area from this width
