Ellie buys a mobile phone in spain for €352.50. her brother jack buys an identical phone from japan for ¥39856. using exchange rates £1 = €1.41, £1 = ¥188. which country is the mobile phone cheaper

The answer to your question is: Japan

Step-by-step explanation:

Mobile cost in Spain = € 352.5

Mobile cost in Japan = ¥39856

Exchange rate = £1 = €1.41

                           £1 = ¥188

Cost of mobile in pounds

                       £ 1 € 1.41

                        x     €352.5

                       x = (352.5 x 1) / 1.41

                       x= £250

                      £1    ¥188

                      x     -¥ 39856

                     x = (39856 x 1) / 188

                     x = £212

Then, it was cheaper in Japan

step-by-step explanation

e2020 got it right

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
