v = veg. sub sales = 4200 – m

.04m = .05(4200 -m) + 51, and .09m = 261, or m = 2900, and v = 1300

5%x (or 0.05x) = the profit from the veggie submarines

0.05x + 51 = the profit from the meat submarines

Therefore, the equation based on the given data would be:

0.05x + 0.05x + 51 = 4200

Combine the same terms

0.10x + 51 = 4200

Subtract 51 to both sides of the equation

0.10x = 4149

Divide both sides of the equation by 0.10 to solve for x

x = $41490 (total sales of veggie submarines)

.05x = $2074.50 (profit from the veggie submarines)

.05x + 51 = $2125.50 (profit from the meat submarines)

To solve for the total sales of meat submarines, divide the profit by 4%.

2125.5 / 0.04 = $53137.50

Answer:

Total sales of veggie submarines = $41490

Total sales of meat submarines + $53137.50

let’s see:

$4200 x 0.05 = 210 dollars for meat submarines.

210 – 51 = 159 dollars for veggies

add it up and get 369 total dollars.
