Answer:
45 %
Step-by-step explanation:
Unproportional. 60/10=6
90/20=4.5
120/30=4
150/40=3.75
As you can see, this is a multiplication root.
y = 4 · x
x = 7 · 3
So solve for x first to solve for y.
x = 7 × 3
x = 21
y = 4 · x
y = 4 × (21)
y = 84
Answer:
cost of bracelet = 25*.05 +4*.45
cost of bracelets = 2(25*.05 +4*.45)
Step-by-step explanation:
One bracelet
Supplies needed:
25 beads and 4 charms
Each bead costs .05 and each charm costs .45
Cost of bracelet = number of beads * cost per bead + number of charms * cost per charm
cost of bracelet = 25*.05 +4*.45
cost of bracelet = 1.2 +1.8
=3.00
To make 2 bracelets
Cost of bracelets =2*( number of beads * cost per bead + number of charms * cost per charm)
cost of bracelets =2*( 25*.05 +4*.45)
cost of bracelets=2( 1.2 +1.8)
cost of bracelets = 2*3
cost of bracelets = 6
