1. Mary is twice as old as her brother Zane. Zane is four years less than
twice as old as his cousin Chase. If
Chase is 4 years old, how old is Mary?

8

Step-by-step explanation:

mary = twice older than zane

zane=four yrs less than twice of chase

chase= 4

therefore;

twice of chase is  8 and zane is 4 years less so

8-4=4

and mary is twice older so

where is the figure

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
