Answer:
7 lawns
Step-by-step explanation:
Let us do this. replace l with lawns mowed and replace day with 4 since the trip is a 4-day trip.
What is 198 + 56?
254.
35l + 189 must be equal to or more than 45(4) + 254.
(45 x 4) + 254 = 180 + 254 = 434
434 - 189 = 245
35l = 245
35/35 = 245/35
l = 7
He has to mow 7 lawns.
Answer:
7 lawns
Step-by-step explanation:
Given:
Airfare = $198 Transportation = $56 Food = $45 per day Length of trip = 4 days
⇒ Total cost of trip = airfare + transportation + 4 x food
= 198 + 56 + (4 x 45)
= $434
Given:
⇒ Amount to make from mowing lawns = total cost of trip - savings
= 434 - 189
= $245
Therefore, he needs to make $245 from mowing lawns to have enough money to pay for the trip.
Given:
Amount earned per lawn mowed = $35 ⇒ number of lawns = amount needed ÷ amount earned per lawn
= 245 ÷ 35
= 7
So he needs to mow 7 lawns to have enough money to pay for the trip.
