Johns total at the deli is $ 7.58
<u>Solution:</u>
Given, John went to the deli on his lunch hour he bought 1.3 lbs of roast beef and 0.6 lbs of cheese both were on sale for $3.99 per pound.
We have to find the nearest cent how much was Johns total at the deli
Now, we know that, total cost = cost of beef + cost of cheese
Total cost = amount of beef bought cost of beef per pound + amount of cheese bought
cost of cheese per pound
Total amount = 1.3 3.99 + 0.6
3.99
Total amount = 3.99(1.3 + 0.6) = 3.99 x 1.9
Total amount = 7.581
Hence, the total amount was $7.58
