Respuesta :

Johns total at the deli is $ 7.58

Solution:

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 [tex]\times[/tex] cost of beef per pound + amount of cheese bought [tex]\times[/tex] cost of cheese per pound  

Total amount = 1.3 [tex]\times[/tex] 3.99 + 0.6 [tex]\times[/tex] 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
