Calculate the interest for a yearinterest/year = percentage × deposit
interest/year = 7.5% × 300
interest/year =

interest/year =

interest/year = 22.5
She will get $22.5 in a year
Calculate interest in 5 yearsinterest in 5 years = interest per year × 5
interest in 5 years = 22.5 × 5
interest in 5 years = 112.5
She will get $112.50 in 5 years
Answer: y = 4
Step-by-step explanation:
To solve, we will isolate the y variable.
Given:
4(y + 4) = 32
Distribute the 4 with multiplication:
4y + 16 = 32
Subtract 16 from both sides of the equation:
4y = 16
Divide both sides of the equation by 4:
y = 4
Step-by-step explanation:
64/(1+1+2)
= 64/4
= 16
1 : 1 : 2
mark = 1×16 = 16
dave = 1×16 = 16
ralph = 2×16 = 32
