Answer:
$45
Step-by-step explanation:
We are given that Tia is buying paper cups and plates.
Number of cups in one package=12
Number of plates in one package=10
We have to find how much Tia expect to pay if each package of cups is $3 and each package of plates is $5.
According to question
[tex]12=2\times 2\times 3[/tex]
[tex]10=2\times 5[/tex]
LCM=[tex]2\times 2\times 3\times 5=60[/tex]
Total number of cups buys by Tia =60
Total number of plates buys by Tia=60
Number of packages of cups =[tex]\frac{60}{12}=5[/tex]
Number of packages of plates=[tex]\frac{60}{10}=6[/tex]
Cost of each package of cups =$3
Cost of 5 packages of cups =[tex]3\times 5=[/tex]$15
Cost of 6 packages of plates =[tex]5\times 6[/tex]=$30
Total cost=15+30=$45
Hence, Tia expect money to pay=$45
