Andre has seven dollars he needs $50 to buy a skateboard each week his grandmother pays him four dollars to complete some chores
SVEN [57.7K]

Answer:

$11

$39

Step-by-step explanation:

Amount Andre has = $7

Amount his grandmother pays him every week = $4

Amount Andre needs to buy a skateboard = $50

how much money does Andre have after the week?

Amount of money Andre has after the week = Amount Andre has + Amount his grandmother pays him every week

= $7 + $4

= $11

Amount of money Andre has after the week = $11

Amount Andre needs more to buy the skateboard = Cost of the skateboard - Amount of money Andre has after the week

= $50 - $11

= $39

Amount Andre needs more to buy the skateboard = $39
