Question 213924
1. if 3 cans of asparagus cost $7.00, How much do 12 cans cost?
A ratio equation is one way:
{{{3/12}}} = {{{7/x}}}
Cross multiply
3x = 7*12
3x = 84
x = {{{84/3}}}
x = $28 for 12 cans

2. if it takes a basket maker 20 days to make 30 baskets, 
how many baskets can be made in 60 days?
{{{20/60}}} = {{{30/x}}}
20x = 60*30
20x = 1800
x = {{{1800/20}}}
x = 90 baskets in 60 days
