Answer:$90
Step-by-step explanation: $30 is the cost. 200 is the percent of Mark-up, so you take 100 percent of 30 and add it together then you get 60. Repeat that step for a total of 90. 100 percent of 30 is 30. So 30+ 30+ 30 = 90.
Answer:
Step-by-step explanation:
Simple interest is given as
S.I = PRT/100
Where
S.I is simple interest
R is rate in %
P is the principal
And T is time in years
So, given that
Principal (P)=£1500
Rate(R) =2%
Time(T)= 3years
Then, we are asked to find amount after 3years
S.I=PRT/100
S.I=1500×2×3/100
S.I= £90
This is the interest Brian will receive
So, the money will amount to
Amount=Principal + interest
Amount = 1500+90
Amount = £1590.
So Brian will have £1590 after 3years
Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2
24 = 12*2 and 8*3
