Answer:
Step-by-step explanation:
for odd terms
first term=5
c.d.=8-5=3
odd terms are given by 5+3(n-1)=2+3n
for even terms
first term=10
c.d.=13-10=3
even terms are given by 10+3(n-1)=7+3n
The cost of turkey sandwiches is $3 and chef salads costs $2.
Two equations can be derived from this question:
12t + 44s = 124 equation 1
12t + 58s = 152 equation 2
Where:
t = turkey sandwiches
s = chef salads
In order to determine the value of s, the following steps would be taken:
Subtract equation 1 from 2
14s = 28
Divide both sides of the equation by 14
s = $2
Substitute for s in equation 1
12t + 44(2) = 124
12t = 88 = 124
12t = 124 - 88
12t = 36
t = 3
