126= 10p+4(p+7)
p=phones
Step-by-step explanation:
Since she sold 7 more accessories than phones, one part would be p+7. 10$ per phone, would be 10p, and $4 per accessory, would be 4(p+7). Add both expressions up.
Answer:
Step-by-step explanation:
A_n = a + (n-1)d
a_n = -2n + 3
when n=1
a_1 = a = -2(1) + 3 = -2 + 3 = 1
when n = 2
a-_2 = -2(2) + 3 = -4 +3 = -1
a_2 = a + d
therefore,
a + d = -1
d = -1 - a
d = - 1 - 1
d = -2
Therefore the sequence is ,
1 , -1, -3, -5, -7.......
