Question

Jenna paid $7.89 for lunch materials that consisted of of a loaf of bread that costs $0.67 and deli ham that costs$6.25 a pound. To two decimal places, how many pounds of ham did jenna buy

Answer 1

She bought 5.58pounds worth of ham

Answer 2

The first step is to subtract the cost of the bread from the total cost to get how much Jenna spent on deli ham.
Since the bread cost $0.67, you'd take $7.89-0.67 which equals $7.22.

Next, we need to figure out how many pounds of ham Jenna purchased.
We know that she spent $7.22 on the ham, and we know that it costs $6.25 per pound.

The way that I would solve this is by cross multiplying.


`(6.25)/(1 pound) = (7.22)/(x pounds)`
When you cross multiply the fractions you get 6.25x = 1(7.22)
Then you just solve for x:
6.25x=7.22
6.25x/6.25 = 7.22/6.25
1.1552 or 1.16 (rounded)

Thus, Jenna purchased 1.16 pounds of deli ham.

Hope this helps!
