Answer: 5 times
Step-by-step explanation:
Let the number of times that he saved $75 be x.
Let the number of times that he saved $150 be y.
Therefore, based on the information given in the question, we can form an equation which will be:
x + y = 8 ...... i
75x + 150y = 825 ....... ii
From equation I,
x + y = 8
y = 8 - x....... iiii
Put equation iii into ii and this will be:
75x + 150y = 825
75x + 150(8 - x) = 825
75x + 1200 - 150x = 825
75x - 150x = 825 - 1200
-75x = -375
x = 375/75
x = 5
He saved $75 5times from his paycheck.
Answer:
40 percent
Step-by-step explanation:
(10/25 ) x 100 = (2/5) x100 = (0.4) x 100 = 40% of the roses was given away.
Because there is no whole number that you can divide into both the numerator and the denominator to get a proper fraction.
I’m pretty sure the answer is 75.4 ft cubed.
Answer:
c = $1.4
p = $2.8
Step-by-step explanation:
two equations can be derived from the question
6p + 5c = 23.80 equation 1
7p + 6c = 28 equation 2
p = plates
c - cups
multiply equation 1 by 7 and equation 2 by 6
42p + 35c = 166.60 equation 3
42p + 36c = 168 equation 4
subtract equation 3 from 4
c = 1.4
substitute for c in equation 1
6p + 5(1.4) = 23.80
p = (23.80 - 7) / 6
p = 2.8
