Answer: the maximum number of drinks Liam can buy is 4 without over exceeding his price limit.
work:
$3.50 for 5 tacos is $17.50
9 - 5 tacos = 4 drinks
4 drinks x $2 = $8
$17.50 + $8 = $25.50 out of $30 price limit

Distribute
remember a(b+c)=ab+ac
we can actually divide both sides by x
5(4x+8)=4(6x-10)
distribute
20x+40=24x-40
minus 20x both sides
40=4x-40
add 40 both sides
80=4x
divide by 4
20=x
Answer:
- After a 90% increase, there is 2,280
- After a 55% increase, there is 2015
- After a 58% decrease, there is 588
Step-by-step explanation:
Assume the original figures are x.
After a 90% increase, there is 2,280:
x * (1 + 90%) = 2,280
1.9x = 2,280
x = 2,280 / 1.9
= 1,200
After a 58% decrease, there is 588:
x * (1 - 58%) = 588
0.42x = 588
x = 588/0.42
x = 1,400
After a 55% increase, there is 2,015:
x * (1 + 55%) = 2,015
1.55x = 2,015
x = 2,015/1.55
x= 1,300
Order:
1,200 ⇒ 1,300 ⇒ 1,400
