Answer:
6 jogs
Step-by-step explanation:
To spend exactly $50
Jags = $1
Jigs = $2
Jogs = $7
If he must buy atleast 1 of each and still spend exactly $50
Hence, the largest number of jogs he can buy can be modeled as :
First obtain the multiples of 7 up to 50
Multiple of 7 up to 50
7 : 7, 14, 21, 28, 35, 42, 49
If $49 is spent on jigs, then he won't be able to purchase jigs.
Hence, the largest amount he can spend on jogs is $42
Thus, he can buy $42 / $7 = 6 jogs
The $8 left can be spent on jigs and jags
Answer:
255 (assuming x is the variable x)
340 (assuming x is the multiplication sign)
See explanation below.
Step-by-step explanation:
I assume that x is the variable x.
25(0.3x-4)-5(1.5x-6)+100·13/4 =
= 7.5x - 100 - 7.5x + 30 + 25 × 13
= -70 + 325
= 255
If my assumption above is incorrect, and x really means the multiplication sign, then we have this:
25(0.3×-4)-5(1.5×-6)+100·13/4 =
= 25(-1.2) - 5(-9) + 100(3.25)
= -30 + 45 + 325
= 340
