This is an expression if she only gets pedicure
y = 35
If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5
So the expression would be
y = 35 + 2.5x
y = 2.5x + 35

Answer:
<h2>
£1,330.46</h2>
Step-by-step explanation:
Using the compound interest formula ![A = P(1+\frac{r}{n} )^{nt}](https://tex.z-dn.net/?f=A%20%3D%20P%281%2B%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7Bnt%7D)
A = amount compounded after n years
P = principal (amount invested)
r = rate (in %)
t = time (in years)
n = time used to compound the money
Given P = £1200., r = 3.5%, t = 3years, n = 1 year(compounded annually)
![A = 1200(1+0.035)^{3}\\ A = 1200(1.035)^{3}\\ A = 1200* 1.108717875\\A = 1,330.46](https://tex.z-dn.net/?f=A%20%3D%201200%281%2B0.035%29%5E%7B3%7D%5C%5C%20A%20%3D%201200%281.035%29%5E%7B3%7D%5C%5C%20A%20%3D%201200%2A%201.108717875%5C%5CA%20%3D%201%2C330.46)
