Answer:
see the explanation
Step-by-step explanation:
Remember that
[tex]1\ week=7\ days[/tex]
To convert weeks to days , multiply by 7
so
[tex]3\ weeks=3(7)=21\ days[/tex]
we know that
Each night Tim's Tacos sell 57 chicken tacos and 89 beef tacos
To find out how many of each type of taco sold after three weeks, multiply the number of taco sold daily by 21 (3 weeks)
Chicken tacos
[tex]57(21)= 1,197\ chicken\ tacos[/tex]
Beef tacos
[tex]89(21)= 1,869\ beef\ tacos[/tex]
