This is a proportion problem.
Compare Dollars to Dollars and Patties to patties.
.
$5.80/12 patties = $7.00/x patties
.
Cross-multiply and solve for x:
5.80x = (12)(7)
.
5.80x = 84
x = 14.48 or 14 patties.
Another method is to find out how much a single pattie would cost:
If 12 patties cost $5.80, than divide $5.80/12 = $0.483 per pattie.
.
If you have $7.00 to spend and each pattie is $0.483 per pattie, than:
7/0.483 = 14.48 or 14 whole patties.
