Liam and his children went into a restaurant and where they sell drinks for $2 each and tacos for 3.50 each .liam has $30 to spend and must buy at least 9 drinks and tacos altogether. if liam decides to buy 5 tacos determine the maximum number of drinks that he could buy

If liam buys 5 tacos (each costing $3.50)

$3.50 x 5 = $17.50

this means he must now take $17.50 from his total $30

$30 - $17.50 = $12.50

he now has $12.50 to spend on drinks

each drink cost $2 and so you must do $12.50 divided by $2 to determine how many drinks liam can buy.

$12.50 divided by $2 = 6 (with $0.50 left over)

therefore, liam can buy 6 drinks, 5 tacos and still have $0.50 change
