Answer:
6 hamburgers
Step-by-step explanation:
Step 1. We figure out how much it would have cost if Becky only bought hamburgers.
18 x $4 = $72
Step 2. We find the difference between the actual price she paid, and the answer above.
$72 - $48 = $24
Step 3. We find the difference between the two different foods she could have bought (hamburgers or hot dogs).
$4 - $2 = $2
Step 4. We divide the answer to step 2 by the answer to step 3.
$24 / $2 = 12
(This is the number of hot dogs - or the cheaper item)
Step 5. We subtract the answer to step 4 from the total number of items that Becky bought.
18 - 12 = 6
(This is the number of hamburgers - or the more expensive item)
Step 6. We check our answer.
12 hot dogs = 12 x $2 = $24
6 hamburgers = 6 x $4 = $24
Total = $24 + $24 = $48
Hope this helps! :)
