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

Respuesta :

She bought 5.58pounds worth of ham
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. 

[tex] \frac{6.25}{1 pound} = \frac{7.22}{x pounds} [/tex]
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!
