Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8
Answer:
-1, -7, -13, -19
Step-by-step explanation:
-2(-3)-7 =6-7= -1
-2(0)-7 =0-7= -7
-2(3)-7 =-6-7= -13
-2(6)-7 =-12-7= -19
A relation is a relationship between sets of values. In math, the relation is between the x-values and y-values of ordered pairs. The set of all x-values is called the domain, and the set of all y-values is called the range.
So, the first 10 suits came with a commission of 5%, so for each suit it was:
250*5%
this is

but this counts for 10 suits, so together his commssion was 10*12.5=125 dollars
and the "extra" 3 suits came with a comittion of 5+3 percent, so 8 percent, which is

for each suit, and 60 in total.
his total comission was 125+60=185 dollars.
