A car rental company advertises a price of
$220 to rent a car for
4 days. At this rate,
what is the cost to rent
a car for a full week?
(Step by step please)

Work Shown:

(220 dollars)/(4 days) = (x dollars)/(7 days)

220/4 = x/7

220*7 = 4*x

1540 = 4x

4x = 1540

x = 1540/4

x = 385

It costs $385 to rent a car for a full week (7 days)

If your teacher considers a week to be 5 days (ignoring the weekends), then you'll need to solve 220/4 = x/5 instead. That would lead to x = 275. I have a feeling that your teacher might want 7 days though.

Side note: In the jump from step 2 to step 3, I used the cross multiplication rule.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
